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

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.

Tycho Brahe Prize 2018 to Andrzej Udalski
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

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.

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.

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

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.

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.

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).

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

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.

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

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
