Launch of the EAS e-Newsletter

The EAS is happy to announce the launch of a new medium. For many years, EAS news was communicated either through the paper Newsletter (which appeared twice per year) or via the short electronic e-News. EAS Council has considered the continuation of the paper Newsletter and has decided to move to another more flexible, modern and attractive way of communication with its members and beyond. Hence the birth of a new medium: an e-Newsletter that combines and replaces the short electronic e-News and the paper Newsletter. Read more

Message from the President
Report to the General Assembly

Council, Staff and our supporting company Kuoni spent a considerable amount of time and effort on the EWASS front. First came the preparation of the meeting we are having in Athens. This exercise was delicate at the beginning for a number of reasons, all having to do with the political and economic situation of Greece in the Summer of 2015. This, contrary to my expectations, created tensions between the in Greece and out of Greece partners. The lack of confidence of the economical establishment outside Greece went as far as imposing that EAS carries alone the risks of the prepayments to organise the event. When one knows that the budget of an EWASS meeting is 3-4 times the EAS annual budget this led to difficult decisions. Having had a very successful EWASS15, the EAS was in a position to take this risk and decided to go ahead. With time going the tensions eased one after the other, leading to a very constructive collaboration. All is well, the decision was right, many thanks to all involved. Read more

EAS policy regarding diversity and non-discrimination

The Council reminds all EAS members about the EAS policy on diversity and non-discrimination. In this policy, the EAS recognizes that diversity among astronomers brings diversity of ideas, methods and sensitivity, which is beneficial to astronomy. In addition, it is critical for the future of astronomy, and science in general, that young people can see evidence that scientists can succeed regardless of, e.g., gender, nationality, ethnic origin, or social origin. The full text of this document is available here.

Future prospects for far-infrared space astrophysics
EWASS symposium 4

The far-infrared (FIR) spectral region enables studies of the thermal dust continuum emission and key atomic and molecular cooling lines, revealing the cold universe, hidden from view at UV or optical wavelengths. Over the past two decades, space missions such as the Infrared Space Observatory, Spitzer, Herschel, Planck, and Akari have revealed the intricate interactions between stars and the interstellar medium of the Milky Way and external galaxies. They have refined our understanding of star formation as a function of cosmic time and of the role of AGNs in galaxy evolution. The new ground-based and airborne submillimeter/FIR facilities, notably ALMA and SOFIA, will allow to continue these studies. However, it is now imperative to start planning the FIR space missions of the future. Read more

Exploring the outskirts of galaxy clusters
EWASS symposium 6

One of the major scientific goal for Athena, the next-generation European X-ray telescope recently selected by ESA as second Large Mission of the Cosmic Vision program, is to determine how baryons assemble and dynamically evolve into galaxy clusters. The outskirts of galaxy clusters are the place where the connection between the highest peaks in the comic matter density and the large-scale structure is established. Read more

X-rays from AGN: looking into the central engine
EWASS symposium 7

Active Galactic Nuclei (AGN) are powered by accretion onto supermassive black holes. X-rays are produced in the innermost region of the flow provide a unique probe of the black hole environment all the way into the event horizon. The X-ray spectral and timing properties carry vital information regarding the space-time, the emission mechanisms for continuum and reprocessed radiation, the nature and dynamics of absorbing gas, and the geometry of the central source and accretion disc.

Interstellar dust and gas coupling: linking observations, models and laboratory astrophysics
EWASS symposium 8

In regions where stars are forming, about one percent of the mass is in the form of sub-micrometer sized dust particles. However small and insignificant these dust grains may seem, they are now recognised as powerful interstellar catalysts and are responsible for most of the production of the simplest (H2) to the most complex (pre-biotic) molecules observed in the Universe. In addition, since dust particles are interacting with the gas, the chemical composition and thermodynamics of a gas cloud forming stars depends on gas-dust interactions. Read more

Stellar and AGN feedback in galaxies: a multi-wavelength perspective of outflows
EWASS symposium 12

Evidence for an intimate connection between the fuelling and growth of supermassive black holes (SMBH) and the evolution of galaxies is now compelling. Not only have SMBHs been found in many galaxies with significant bulge components, but correlations also exist between the black hole mass and bulge properties such as stellar mass and velocity dispersion. Even beyond that, there is now evidence of massive black holes in low mass galaxies. The physical processes underpinning this relationship are known collectively as feedback. Outflows induced by the nuclear activity might play a critical role as a feedback mechanism, since their energy output might regulate the growth of the black holes and their hosts at least for massive galaxies.

New classes and unique events in time domain astronomy
EWASS symposium 14

Modern time-domain optical surveys are discovering new types of transient phenomena that defy the traditional supernova (SN) classes: superluminous SNe (SLSNe) are very luminous explosions that, despite concentrated effort, remain mostly unexplained; rapidly evolving SNe pose serious challenges to traditional models; a newly discovered class of tidal disruption events (TDEs) has sparked a flurry of theoretical work to try and explain the observed properties.

Exploring pulsar formation, evolution and magnetic field: from low mass X-ray binaries to magnetars
EWASS symposium 15

Recent observations of neutron stars in multiple wavelengths, both from space and ground-based observatories combined with ongoing monitoring have revealed their rich and diverse behaviour, ranging from the explosive magnetars to the steady rotation-powered pulsars and the accreting millisecond pulsars. It is now widely recognised that a key parameter behind this broad phenomenology is their magnetic field and a lot of effort has been put into modelling and simulating these systems. Read more

Magnetic helicity in Sun and stars: from dynamo action to eruptive phenomena
EWASS symposium 17

The intriguing topic of magnetic helicity in the Sun and magnetically active stars was the overarching theme of this two-day Symposium. The sheer energy of magnetic fields in the atmospheres of stellar objects was once thought to be solely responsible for major stellar eruptions, from solar flares to orders-of-magnitude stronger gamma-ray bursts in flare stars, pulsars, and magnetars.

The effects of solar and stellar magnetic activity on planets
EWASS special session 7

This Special Session brought together observers/theoreticians whose diverse research interests are linked with solar and stellar activity and its effect on orbiting planets. The magnetic activity of cool stars (flares, winds and coronal mass ejections) have a direct impact on planets. This activity varies with the mass, age and rotation rate of the star and can be damaging for life, even in the case of a fairly inactive star like the Sun. Read more
