New EAS membership arrangements
Proposal to be approved formally by the EAS General Assembly
The EAS aims to represent European professional astronomy and space science, and to do this optimally a large membership base is required. EAS Council has therefore developed a new model for EAS membership, in which membership will be free and practically automatic for most members of one of the EAS Affiliated (National) Societies. The impact of this change on the EAS and its finances has been carefully evaluated, and Council thinks it can be managed. ▸ Read more
EAS will maintain ordinary and junior members, where the latter are PhD candidates. For all EAS members who are proposed by Affiliated Societies and comply with EAS membership criteria, EAS membership will be free of charge. The Affiliated Societies have already been informed and are generally very positive. Affiliated Societies will pass on membership information the EAS, but
may well need to ask individual consent from their own members, and may
need to inform them of data protection issues. Your own National Society
will contact you about this. Colleagues who are not members of an Affiliated Society, or who cannot be (for instance because no such Society exists where they reside) can still become members of the EAS but will have to apply directly. Such 'independent' members will continue to pay a membership fee to the EAS.
European Regional Office of Astronomy for Development
Joint venture by Leiden University and the EAS
The IAU Office of Astronomy for Development (OAD) was set up in 2011 as a joint venture between the IAU and South Africa to implement the IAU Strategic Plan "Astronomy for Development 2010-2020" and its mandate has been extended. Besides establishing OAD Task Forces for selecting and implementing astronomy-for-development activities, the OAD has initiated nine Regional OADs (ROADs) and three language expertise centres (LOADs) throughout the world. ▸ Read more
So far, most of Europe has not been covered by any of the existing ROADs. Although Europe is a region in which astronomy is highly developed, the use of astronomy as a tool for achieving several of the UN Sustainable Development Goals is very relevant for the Continent. The proposal for establishing a Leiden—EAS European ROAD was approved unanimously by the EAS Council and by the OAD Steering Committee.
The new ROAD will carry out and coordinate relevant astronomy-for-development activities in all three Task Force areas defined in the IAU Strategic Plan — Universities/Research, Schools/Children and Public Outreach, focusing on accomplishing the UN Sustainable Development Goals in Europe. These tasks will be carried out in cooperation with existing activities of pan-European and national astronomical organisations. IAU press release on the launch of the European ROAD

Tycho Brahe Prize awarded during the EWASS meeting in Liverpool
The 2018 Tycho Brahe Prize is awarded to Prof. Andrzej Udalski (University of Warsaw, Poland) in recognition of the role as driving force behind OGLE (Optical Gravitational Lensing Experiment), one of the most successful and longest running sky-variability surveys ever undertaken. OGLE has made a significant impact on many fields in modern astrophysics. ▸ Read more
Andrzej Udalski was born in Łódź,
Poland. He graduated in 1980
from the Faculty of Physics at the
University of Warsaw and
obtained there his PhD thesis in
1988. He then moved to York
University in Toronto, Canada as a
postdoc and returned to Poland
after two years. He obtained his
habilitation at the University of
Warsaw in 1995 and became
professor in 2000. He directed the
Astronomical Observatory from
2008 to 2016.
Professor Andrzej Udalski's scientific career has been connected with the OGLE survey since the early 1990s. He put into practice the early idea by Bohdan Paczyński to regularly monitor millions of stars to search for sudden brightening caused by gravitational lensing by hypothetical dark massive objects in the halo of the Milky Way. OGLE has produced top ranked discoveries across many fields of modern astrophysics for almost three decades.
Lodewijk Woltjer Lecture 2018 to Conny Aerts
Lodewijk Woltjer Lecture awarded during the EWASS meeting in Liverpool
The 2018 Lodewijk Woltjer Lecture is awarded to Prof. Conny Aerts (KU Leuven, Belgium and Radboud University Nijmegen, the Netherlands) for outstanding work in stellar physics, in particular in the field of asteroseismology. ▸ Read more
Prof. Conny Aerts graduated as mathematician from Antwerp University in 1988 and defended her PhD thesis in astrophysics at KU Leuven in 1993. She continued her career as Postdoctoral Fellow of the Research Foundation Flanders until 2001, defining an independent research track and performing numerous stays abroad in Europe, Chile and the USA to achieve it. She was appointed as Lecturer (2001), Associate Professor (2004), and Full Professor (2007) at KU Leuven. Since 2011, she is Director of the Institute of Astronomy in Leuven. Since 2004, she also leads the Chair in Asteroseismology at the Radboud University Nijmegen. She is the recipient of 2 ERC Advanced Grants (2009 and 2016) and was awarded the Francqui Prize in 2012. Conny Aerts is an Honorary Fellow of the Royal Astronomical Society since 2010, and Commander in the Order of Leopold since 2016, the highest civilian recognition offered through Royal Decree by His Majesty King Philippe for services to the Kingdom of Belgium.
In 2009, Prof. Conny Aerts was awarded an ERC Advanced Grant, PROSPERITY to evaluate stellar models from CoRoT and Kepler space asteroseismology. Under her leadership, her PhD students made major contributions, such as the discovery of non- radial pulsation modes, dipole mixed modes, and non-rigid rotation in red giants, following her earlier detections of core overshooting and core rotation in massive stars. This culminated in the prestigious 2012 Francqui Prize, also termed Belgian Nobel Prize. Conny Aerts was the first woman to receive this prize in the option Science & Technology since its creation in 1933. The ERC offered her a second Advanced Grant, MAMSIE, in 2016 to bridge stellar physics and 3D hydrodynamics with the aim of remedying shortcomings in stellar evolution theory of massive stars.
MERAC Prizes 2018 to Sandrine Codis, Renske Smit and Martin Pertenais
MERAC Prizes for the Best Doctoral Thesis awarded during the EWASS meeting in Liverpool
At the EWASS 2018 meeting in Liverpool, the 2018 MERAC Prizes for the Best Doctoral Thesis were awarded. The winner in the category Theoretical Astrophysics was Dr Sandrine Codis for the study of the imprint of the large-scale structure of the Universe on galaxy formation and cosmology. The prize in Observational Astrophysics was awarded to Dr Renske Smit for the observational characterisation of the physical properties of the galaxies that formed in the first billion years of cosmic time. Finally, the laureate in the category New Technologies was Dr Martin Pertenais for a PhD thesis on cutting-edge concepts of compact polychromatic spectropolarimeters adapted to astrophysical space mission requirements in the UV domain. ▸ Read more
The FONDATION MERAC (Mobilising European Research in Astrophysics and Cosmology) is a non-profit foundation started in 2012 with headquarters in Switzerland to recognise and support young European astronomers. There are yearly three MERAC Prizes awarded by the European Astronomical Society. The prizes of 20,000 Euro are for each of the three categories (Theoretical Astrophysics, Observational Astrophysics, and New Technologies). The prizes alternate by year for Best Early Career Researcher Prizes (on odd years), and Best Doctoral Thesis Prizes (on even years). The awardees are also eligible for further support from the FONDATION MERAC.
Renske Smit's doctoral research focused on the study of very distant galaxies, seen in the first few billion years of cosmic history, using the Hubble and Spitzer Space Telescopes. Her studies were among the first to obtain genuine insight into the physical conditions of these galaxies, paving the way for detailed follow-up studies with ground-based instrumentation. Her research established that emission lines associated with the formation of massive, young stars often dominate the broadband flux of distant galaxies. This work resolved a major discord between observations and theoretical models of the evolution of galaxies in the early Universe. Renske Smit's innovative work also enabled her to identify new galaxies in the Epoch of Reionisation; spectroscopic follow-up of these sources with the Atacama Large Millimeter Array allowed her to obtain the first measurement of velocity structure in galaxies at this early epoch. She participated in efforts to detect even more distant (z ~ 8—9) galaxies, spectroscopic follow-up of which yielded spectacular confirmation of their redshifts via the Lyman- alpha emission line, breaking two consecutive records for the most-distant galaxy known to science. As a member of the NIRSpec Guaranteed Time Observations (GTO) Galaxy Assembly team, Renske Smit is now preparing for the forthcoming revolution promised by the launch of the James Webb Space Telescope.
The 2018 MERAC Prize for the Best Doctoral Thesis in New Technology is awarded to Dr Martin Pertenais (DLR, Germany). Martin Pertenais has obtained an optical engineer degree from the prestigious Engineer School Institut d'Optique Graduate School (IOGS) in Paris and a Master in photonics from the University of Jena. He then undertook a PhD thesis in instrumentation for astrophysics at the Institut de Recherche en Astrophysique et Planétologie in Toulouse and at the Paris Observatory on "Stellar UV and Visible spectropolarimetry from space", under the supervision of Coralie Neiner and Pascal Petit. This allowed him in particular to successfully lead the Arago Payload consortium and to innovate in new technologies for spectropolarimetry. After his PhD thesis, he moved on a position at DLR as the Optical System Engineer for PLATO. In parallel, he keeps working on new spectropolarimeter designs and co-supervises a PhD student on this topic for the NASA mission LUVOIR.
EWASS in the spotlight
Press Office report for EWASS 2018
Every year EWASS brings together more than a thousand astronomers and space scientists to discuss a plethora of topics in cutting-edge research. It is also a perfect occasion to place astronomy research in the spotlight of the national and international media. At the EWASS 2018 meeting in Liverpool, held jointly with the RAS National Astronomy Meeting, the communication between astronomers and the press was organised by the Press Office, staffed by Robert Massey, Helen Klus, Morgan Hollis, Anita Heward and Marieke Baan. ▸ Read more
A total of 14 press releases on science presented at EWASS 2018 were issued. These press releases were selected from a shortlist of 46 abstracts followed up as possible media stories out of the 1454 total abstracts submitted to EWASS 2018. They covered topics ranging from giant solar tornadoes to magnetic hotspots on neutron stars to 3D maps of the infant Universe. All of these releases were led by authors from European institutions. Five releases featured the work of post-graduate students, giving media experience and profile to early careers researchers.
Journalists attending the meeting included Sue Nelson (ESA TV), Paul Sutherland (freelance), Paul Wood (Nature Astronomy), Dan Clery (Science), Sue Bowler (A&G), Osnat Katz (Popular Astronomy), Josh Hayes (Jodcast) and Keith Smith (Science).
Overall, the volume and quality of the media coverage for EWASS 2018 was extremely good. The top story was the astro-ecology project led by Claire Burke and Maisie Rashman, which was featured on the BBC Six O'Clock News (3rd April), as well as BBC Radio Merseyside, BBC Africa, BBC World Service and Discovery Channel TV in Canada. An interview with Richard Massey on BBC Breakfast (6th April) was followed by a Facebook Live session that had 11K views, and Jane Greaves was interviewed on BBC Radio 4's Today Programme (5th April).
Print and online outlets covering EWASS 2018 included the Independent, the Telegraph (print and online), Sky News, Daily Mail, the Express, the Mirror, Newsweek, the New York Times, Forbes, BBC Mundo, Scientias.nl, Le Monde, El Mundo, Süddeutsche Zeitung, The Hindu, New Scientist, IFL Science, National Geographic, Kijk Magazine, Focus, Science et Vie, Space.com, UPI and Europa Press.
Gaia: the billion-star Galaxy census: at the threshold of Gaia DR2
EWASS 2018 symposium 2
The GREAT (Gaia Research for European Astronomy Training) initiative is a pan-European research network involving over 500 researchers in 20+ countries with a common interest in aiming to maximise the science potential of Gaia. This 11th GREAT network annual plenary meeting was co-located at the EAS 2018 EWASS, constituted as Science Symposium 2. It was organised in six sessions, with 34 presentations, over the days 5-6 April 2018. ▸ Read more
Following the successful open model adopted at the 5th GREAT Plenary in 2012, the community were invited to submit their proposed talk titles and abstracts on the meeting wiki. The final meeting programme was then generated by the SOC based on those contributions. The symposium was attended by well over 100 people. All sessions were well attended, with lively discussion after each presentation.
The second session of the symposium was dedicated to an eagerly anticipated preview of the contents of Gaia DR2 (released on April 25 2018). Brown revealed the actual numbers of sources that are contained in the various Gaia DR2 data sets and this was also the subject of an ESA press release at the same time. A short YouTube interview on Gaia DR2 appeared on the same day. In subsequent presentations De Angeli detailed the photometric contents of Gaia DR2, while Hestroffer and Katz covered the solar system objects and the Gaia DR2 radial velocities. Katz showed a spectacular all sky map of the median radial velocities of stars, showing beautifully the differential rotation of the Milky Way disk. Mora closed the session with a demonstration of the Gaia online archive facilities.
The third session continued with a presentation by Prusti on the status of the Gaia mission in which he highlighted the role of the Gaia catalogues in solar system navigation and the study of solar system bodies through occultations. Cropper discussed in detail the radial velocity spectrometer on board Gaia and Walton provided an update on the GREAT networking activities. Kruszynska discussed the possibilities for photometric microlensing studies with the Gaia data, while de Bruijne and Vallenari both presented open cluster studies with Gaia DR1 data.
The topic of open clusters was continued by Casamiquela in the fourth session, where she discussed the results from the OCCASO survey. Silverwood then presented the progress on studies of the local dark matter density and this was followed by two talks on the combination of Gaia and spectroscopic survey data. Anders discussed the prospects for chemo-kinematics with Gaia, while Coronado presented results on the calibration of spectroscopic distance indicators which can be employed to infer distances in cases where the Gaia parallaxes are not precise enough. Mor discussed a new and fast approach to the inference of the Milky Way IMF and star formation history through comparisons of the Besançon Galaxy model to Gaia data. Yen then revisited open cluster studies using a combination of Gaia and HSOY astrometric data.
In the final session Font presented her predictions for tidal stream studies with Gaia DR2 data. Sahlholdt presented tests of asteroseismic radii for Kepler stars which are done by predicting parallaxes from the radii and comparing those to the Gaia DR1 parallaxes. Mackereth presented his mapping of the Milky Way disk in terms of populations of different [alpha/Fe] ratios using the combination of APOGEE and TGAS data. Fusillo discussed the prospects for Milky Way studies through white dwarf populations and the role of upcoming spectroscopic surveys such as WEAVE and 4MOST. The symposium was closed by Pedersen who discussed plans for the use of Gaia parallaxes in the asteroseismic modelling of intermediate- and high-mass stars.
In addition to the main speaker programme, 9 posters were presented.

Galaxy formation through cosmic time: synergising theory and observations in the era of a large facilities
EWASS 2018 symposium 3
The past few years have seen state-of-the-art observatories, such as the Hubble Space Telescope, Sloan, Spitzer and Subaru, providing tantalising glimpses of galaxy formation, from the earliest galaxies assembling in the infant Universe to evolved systems in the local Universe. These observations have shed light on the redshift evolution of a number of key galaxy properties such as their luminosity functions, the cosmic stellar mass/star formation rate densities, dust masses and (mass-metallicity) scaling relations. ▸ Read more
Despite this progress, a number of compelling outstanding questions, regarding galaxy formation and reionization, persist including:

High resolution solar physics — the dawn of a new era
EWASS 2018 symposium 4
Within the next decade solar physics will have the opportunity to probe the Sun as never before, with the advent of two 4m ground-based solar telescopes: DKIST (Daniel K. Inouye Telescope), due to see first light in late 2019, and EST (European Solar Telescope) planned to achieve first light in 2027. With state-of-the-art instrumentation, they will provide the most sensitive diagnostics of the thermal, dynamic and magnetic properties of the plasma in the solar atmosphere, at the highest spatial resolution (~25 km), and over the most scale heights available on any solar telescope, on the ground or in space. ▸ Read more
These new facilities will enable us to address fundamental questions related to the emergence and evolution of small-scale magnetic field concentrations, and their role in the dynamo processes that control the cyclic evolution of the global magnetic field, as well as their interaction with pre-existing fields - interactions that drive the solar wind and generate global explosive activity.

Relativistic astrophysics, in memory of Stephen Hawking
EWASS 2018 symposium 5
During the last 50 years General Relativity has become the main theoretical concept of modern astrophysics and has seen many breakthroughs in the last few years. During the symposium we discussed the current theoretical understanding of relativistic astrophysics and observational frontiers (e.g. including results from missions like XMM-Newton, NuSTAR, INTEGRAL, Chandra and EVN) as well as the developments of new observational facilities (e.g. Virgo and LIGO, GRAVITY, Event Horizon Telescope, and Large Synoptic Survey Telescope). ▸ Read more

Software in astronomy
EWASS 2018 symposium 6
The six-session Software in Astronomy Symposium was held on Wednesday and Thursday, April 3-4. Each of the six sessions focused on a different aspect of research software, covering not only specific software packages, but also computational techniques used in data mining and machine learning, open services, software development training and techniques, and getting credit and citations for computational methods. Several sessions included a free-form period in which participants could ask questions, discuss issues, and share information. The last session of the Symposium was a lively moderated discussion among attendees with particular interest in software publishing. ▸ Read more
The first session focused on software engineering and sustainability, education for better software, and the ecosystem around Python in astronomy. It set the stage for the Symposium, featuring a variety of topics of importance when discussing astronomy research software. Alice Allen (ASCL, US) moderated the session. In the inaugural talk, John Wenskovitch (Virginia Tech, US) opened his presentation with a quote by computer scientist and professor Carole Goble, stating that software is "the most prevalent of all the instruments used in modern science." This was reiterated by others throughout the symposium. Wenskovitch provided statistics on software use and development activities by academics, among these that 92% of academics use software and 38% spend at least 20% of their time developing software.
Amruta Jaodand (ASTRON, NL) moderated the third session of the Symposium, which featured talks on different software packages. Several novel software packages were presented, including a new cosmological code that should be more than 30 times faster than the well-known Gadget code, and software packages to for handling data cubes. A highlight of the session was the presentation by Maisie Rashman (LJMU, UK) on the novel use of astronomical software in conservation biology. Her team have developed a pipeline using astronomy techniques to identify and track animals; their goal is to create a fully automated system for species identification, population tracking, and combating poaching using drones.
Astronomy leads most sciences in providing many open services, particularly data and ways to get access to and use data. The fourth session of this symposium was devoted to open and transparent data services. It was moderated by Andrew Pollock (USheffield, UK), and highlighted some of the new and ongoing services available to not just professional astronomers, but also to students and other interested parties.
Finally, session 6 was devoted to software publishing. This meeting-within-a-meeting was an opportunity for journal editors and publishers and referees, abstract services, and others associated with research software publication to discuss how best to include research software in the scholarly record, improve the sustainability and reproducibility of research articles, and share information on issues and possible solutions. The session was open to all, and researchers and software authors also attended. The agenda had three main items on it: journal software policies, ratings for numerical reproducibility, and improving instructions for authors and referees. The session was moderated by Rein Warmels (ESO, DE) and Alice Allen (ASCL, US), and was very well attended by editors from, amongst others, Science, MNRAS and the AAS Journals.
All in all, the symposium was a big success, and a more complete coverage of the symposium is posted on the ASCL blog.

Supernova diversity: prospects and challenges for next-generation surveys
EWASS 2018 symposium 7
Modern wide-field time-domain optical surveys are discovering supernovae (SNe) at a dramatically increased rate compared to the past. Thanks to the ever-increasing quality and quantity of data from these surveys, it has become clear that there is real diversity in the standard SN classes. However, it is still uncertain if this diversity is predominantly caused by different progenitor channels, explosion mechanisms, binary-star interaction, or properties of the explosion environments. Understanding this diversity is now a key objective in the SN research field and poses serious challenges to traditional SN taxonomy, requiring a rewrite of the historical classification scheme. ▸ Read more
Moreover, among the discovered transients are many rare and peculiar events that fall outside the standard SN classes. New strategies for the next-generation surveys are required to identify these peculiar transients more promptly, in order to avoid potentially unusual SNe being mislabelled as ordinary. This symposium aimed to bring together observers and theoreticians to address these issues and develop new techniques for classification in the modern SN era. The symposium spanned six sessions over two days, with 70-80 participants attending each session. Each block was dedicated to a different topic.
The final session was dedicated to the next-generation of surveys such as the Large Synoptic Survey Telescope (LSST), which will compound this classification problem by discovering hundreds of thousands of transient events per year, many of which will push the boundaries of our observationally-defined SN classes.
The ISM as a window onto galaxy evolution
EWASS 2018 symposium 9
Symposium 9 at EWASS 2018 brought together researchers with areas of expertise spanning the entire electromagnetic spectrum, and the full range of cosmic time, in order to highlight the interdependence of all aspects of understanding galaxies through their ISM. In the study of the ISM in galaxies, there can be a disconnect between investigations which explore the cold ISM via FIR-to-radio emission, and investigations which exploit the energetic shorter wavelengths where excited gas emits. We were therefore glad that our symposium featured many pieces of work which showcased the value of combining these two avenues of study. ▸ Read more
Simulations of galaxies - via both hydrodynamics and radiative transfer - are becoming ever more detailed and sophisticated; our symposium's contributors spoke on how simulations of the hot ISM are now directly informing and predicting the environments in colder regions (and vice-a-versa) with increasing precision.
The physics and chemistry of planetary atmospheres
EWASS 2018 symposium 10
The challenge of correctly capturing the physical and chemical properties of planetary atmospheres across a broad parameter space is one of the biggest challenges in the theoretical modeling of planets. Symposium 10 brought together 1D and 3D modelers which all work on different levels of consistency and complexity. This symposium show-cased newest technology developments, such as the application of neuronal networks in retrieval techniques. An overview of the challenges inherently present in complex modeling and how to overcome them, was also given. ▸ Read more
Alongside the 10 planetary bodies in our own Solar System with
significant atmospheres, the more than 4000 exoplanets known include
hot lava and giant gas planets, together with both warm and cool
mini-Neptunes and super-Earths. None of these planets resembles our
solar system planets. Planetary atmospheres have proven to be
incredibly diverse and are comprised of a mixture of materials in
different phases (gas, clouds, aerosols, hazes). Understanding the
impact, for example, chemical and radiative, of these species and
their interplay with the circulation and radiation, particularly in
3D, is vital to correctly interpreting observations from the ground
(e.g. VLT) and from space (e.g. ARIEL, JWST, CHEOPS, PLATO).
The next sessions dealt with atmosphere modeling. Understanding exoplanet
atmospheres requires a good amount of modeling on global, weather
scales and on local, chemical scales in order to derive a concise picture
from the snippets of information that are available from
observations. Cloud formation on Earth is utterly complex as Ian
Boutle from the MetOffice outlined. Yet, a combination of
computational chemistry and fundamental physics modeling has
provided a good amount of insight for exoplanet clouds as shown by Christiane
Helling. She explained why clouds can not form in phase
equilibrium. Peter Woitke presented a fast equilibrium gas chemistry
code available to the community in combination with an extensive data assessment exercise. Both, code and assessment catalogues are online available. Olivia Vernot presented a beautiful review on 1D kinetic gas-chemistry modeling including all the different models
available, and she discussed necessary future improvements
for interpretations of the future observations performed with JWST
and ARIEL. Modeling gas and cloud chemistry requires a good knowledge about
element abundances. Martin Asplund demonstrated which sophistication
the element abundance determination for stars has reached and that
this methodological knowledge is also available to the exoplanet
