Message from the President
Roger Davies, the new EAS President

It is an honour and a privilege to be taking over as President of the EAS. I follow Thierry Courvoisier who was been President of the Society for seven years and my first act is to recognise the huge contribution Thierry has made to the Society. He presided over the creation of EWASS (transformed from the earlier JENAM) which has become the annual focal point of the Society's activity. Under Thierry the Society grew in both membership and influence, and it is thanks to his leadership that I am taking over a Society in strong health. Read more

EWASS registration fees
How to balance financial risk, income and expenditure

The yearly European Week of Astronomy and Space Science (EWASS) is going from strength to strength, and is developing into the main regular meeting in our field in Europe. The organisation of EWASS is driven by a need for further homogenisation and professionalisation of the meetings, while at the same making them more attractive for a broad audience. But organising such large meetings professionally comes at a cost. Read more

Comparing simulations and observations of the varying scales of star formation
EWASS 2017 symposium 3

The formation of stars is of fundamental importance in virtually every field of astrophysics, from the birth of planetary systems to the life-cycle of matter within galaxies. Stars are born in the densest regions of molecular clouds, but this process is inefficient. The physical mechanisms responsible for determining the star formation efficiency remain the subject of debate. Possible causes, such as turbulence, magnetic fields and stellar feedback, can operate over a vast range of physical scales, rendering it highly challenging to determine the relative importance of each process.

Astrophysical jets and outflows - synergies from compact objects to protostars
EWASS 2017 symposium 4

Astrophysical jets are produced by a wealth of objects, from stars being born, to stars collapsing and dying, to various flavours of dead stars. The collimated outflows in each scenario are launched due to the process of accretion, whether it be onto a young stellar object, from a magnetized hot flow around a black hole, or during a stellar collapse and the production of a gamma-ray burst. After the birth of jets, they accelerate, escape the gravitational field of their birthplace, before injecting energy into and drive chemistry in their surroundings. In planet forming proto-stellar disks the outflowing material might even affect planet migration. Thus there are a multitude of processes taking place at various stages and on different scales.

Properties and evolution of accreting compact objects in low and high mass X-ray binaries
EWASS 2017 symposium 10

EWASS symposium 10 on "Properties and evolution of accreting compact objects in low and high mass X-ray binaries" provided a unique opportunity to bring together specialists from very different fields, working both on high and low mass X-ray binaries. Although emissions across the entire electromagnetic spectrum from these systems are often produced by different physical processes, both type of binaries share a number of theoretical and observational challenges that benefit from the exchanges of information and expertize between different international scientific collaborations.

A multi-messenger look at the origin of gamma-ray bursts
EWASS 2017 symposium 11

We are currently living in the era of multi-messenger astronomy. We have gamma-ray and X-ray observations from active space missions such as Fermi, Swift, MAXI, INTEGRAL, Konus, AGILE, NuSTAR, CALET, Lomonosov and AstroSAT; and afterglow observations in radio (e.g. MeerKAT), optical and X-ray. Future facilities like CTA, Athena and SVOM are coming up. It is now more important than ever to connect our theoretical understanding of gamma-ray burst (GRB) physics to these multi-wavelength observations. Furthermore, after the discovery of astrophysical neutrinos by IceCube and that of gravitational wave signals by LIGO, the role that GRBs may play in these new fields of astrophysics is now being actively investigated.

Astroinformatics: from big data to understanding the Universe at large
EWASS 2017 symposium 14

Astroinformatics is a full fledged new discipline emerging from the need of extracting new knowledge from complex all-sky surveys and responding to the ever-increasing astronomical data-deluge. It is a multi-disciplinary science combining the fields of astronomy, computer science and advanced mathematics and statistics. It combines machine learning, modern database technologies, and complex data models to reveal correlation, cluster unlabeled data, identify outliers etc. and in general extend our knowledge about the Universe in terms of classes of objects as well as individual objects.

Scientific synergies enabled by SKA, CTA and Athena
EWASS 2017 symposium 15

EWASS symposium 15 was focused on the scientific synergies enabled by SKA, CTA and Athena, the unprecedented capabilities of which will deliver transformational science during the next several decades. The three observatories will cover distinct portions of the electromagnetic spectrum (the radio band for SKA, the X-ray band for Athena and the GeV-TeV band for CTA) and the talks in the symposium showed that the fully-fledged multi-messenger astronomy enabled by SKA, CTA and Athena will lead to address outstanding scientific questions, which are still largely unanswered.
