Linking gas and star formation throughout cosmic time
EAS 2020 Symposium 3

Symposium 3 focused on the relationship between gas content and star formation in galaxies and its evolution with cosmic time. It is very well established that gas is the fuel for star formation: its chemical and dynamical properties indeed determine how it cools, fragments and collapses into stars. Furthermore, the physical processes that regulate star formation are imprinted on the motions and abundances of the gas. To gain a unified view of the interplay between different gaseous phases and star formation, panchromatic observations from rest-frame UV to radio wavelengths are required. Read more

Stellar and gas kinematics in galaxies across cosmic time, connecting observations with theory
EAS 2020 Symposium 6

In the era of large integral field spectroscopic surveys (e.g., Atlas3D, CALIFA, MaNGA, SLUGGS, KROSS, SAMI), and ever improving galaxy formation simulations (e.g. Illustris, EAGLE, Horizon, Magneticum, NIHAO), it is key to bring together experts in all aspects of galaxy kinematics to discuss the physical processes that shape the morpho-kinematic evolution of galaxies. Symposium S6 of the virtual EAS 2020 Annual Meeting provided this opportunity. S6 was split into 6 sub-sessions covering the main aspects of stellar and gas kinematics. Read more

The Magellanic Clouds in the 2020s: a spectroscopic perspective
EAS 2020 Symposium 7

The Magellanic System has long been instrumental in driving our understanding across many fields of astrophysics, ranging from its importance in a cosmological context and the determination of the Hubble constant to the study of astrophysical phenomena under different environmental conditions. Deep, wide-field panchromatic photometric surveys (including the VMC, SMASH and DES) have measured the distribution, ages and masses of the faintest stars, uncovering unmistakable signs of interactions between the Magellanic Clouds as well as identifying a host of ultra-faint dwarf satellite galaxies associated with the System.

Common-envelope systems: progenitors, mergers and survivors
EAS 2020 Symposium 8

The study of the common-envelope (CE) phase has raised an increasing interest over the years in both observational and theoretical fields. Nearly 400 papers with the phrase "common envelope" in the abstract are listed in the ADS for 2016-2019, but no major meeting on the topic has been organized in the recent years in Europe. The goal of the S8 session was to discuss the latest advances in the studies of CE evolution on both theoretical and observational fronts. Read more

Extremes in accretion onto strongly magnetised neutron stars: observations vs. theory
EAS 2020 Symposium 9

Neutron stars (NSs) are known as natural laboratories to study physics under extreme conditions of high density, strong magnetic and gravitational fields. The strength of the magnetic field at the NS surface can exceed the maximal magnetic field strength achievable in labs by a few million. A number of strongly magnetized NSs belong to close binary systems, and their luminosity in X-rays is powered by accretion when a NS catches and absorbs material from its companion in a binary. Extreme accretion regimes emphasize specific features of the interaction between radiation and matter, providing an opportunity to use the observational data in tests of physics under extreme conditions.

The Local Group in context: galaxies in the Local Volume as a testbed of cosmology
EAS 2020 Symposium 11

Faint dwarf galaxies have traditionally been discovered and studied in our immediate cosmic neighborhood, the Local Group of Galaxies, as satellites of the Milky Way and Andromeda. Simulations based on the ΛCDM model of cosmology have struggled to reproduce several aspects of these nearby satellite galaxy systems, resulting in a number of "small-scale challenges". Since their identification, substantial theoretical progress has been made in addressing many of these challenges, including improved modelling of baryonic effects in hydrodynamical simulations, as well as a flurry of other proposed solutions within and outside of the ΛCDM paradigm. However, these are often implicitly tailored to the Local Group due to the preponderance of data from our immediate neighborhood. Read more

Quenching cluster galaxies in the cosmic middle ages
EAS 2020 Symposium 14

Galaxy clusters and groups represent an extreme environment for galaxy formation and evolution. In the local Universe, this leads to a wide variety of differences in galaxy properties such as colours, star formation rates, gas content, and morphologies between cluster and field galaxies. These differences are, however, much smaller in the high-redshift Universe (z ≳ 1.5), implying that the effect of the cluster environment first sets in at intermediate redshift (0.3 ≲ z ≲ 1.5). This Symposium brought together both observational and theoretical astronomers with an interest in this intermediate phase of galaxy evolution, giving the communities an opportunity to update each other on recent progress, identify the shortcomings in current models, and discuss which future observations and simulations will be most beneficial to making progress in this field.

XMM-Newton: current scientific highlights and future prospects
EAS 2020 Symposium 16

The 20 years of XMM-Newton observations have dramatically changed and increased our understanding of all astronomical X-ray emitting sources, from the solar system objects in our neighborhood to distant AGN and clusters of galaxies. The symposium celebrates XMM-Newton's 20th anniversary by highlighting its current scientific achievements. In addition, XMM-Newton is expected to continue to provide such observations for the coming decade as one of the leading X-ray facilities. In the early 2030s XMM-Newton will be replaced by ESA's next generation of large X-ray observatory, Athena. Thus, permanent access to the X-ray sky will be provided for the astrophysical community by ESA. Read more
