Galaxies living in rich environments are suffering different perturbations able to drastically
affect their evolution. Among these, ram pressure stripping, ie the pressure exerted by the …

In a growing number of galaxy clusters diffuse extended radio sources have been found.
These sources are not directly associated with individual cluster galaxies. The radio …

The gas surrounding galaxies outside their disks or interstellar medium and inside their virial
radii is known as the circumgalactic medium (CGM). In recent years this component of …

Abstract We introduce the Virgo Consortium's Evolution and Assembly of GaLaxies and their
Environments (EAGLE) project, a suite of hydrodynamical simulations that follow the …

Aims. The eROSITA Final Equatorial-Depth Survey has been carried out during the
performance verification phase of the Spectrum-Roentgen-Gamma/eROSITA telescope and …

The evolution of the large-scale distribution of matter is sensitive to a variety of fundamental
parameters that characterise the dark matter, dark energy, and other aspects of our …

The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

We detect a weak unidentified emission line at E=(3.55–3.57)±0.03 keV in a stacked XMM-
Newton spectrum of 73 galaxy clusters spanning a redshift range 0.01–0.35. When the full …

Radiation, winds, and jets from the active nucleus of a massive galaxy can interact with its
interstellar medium, and this can lead to ejection or heating of the gas. This terminates star …

Numerical simulations have become a major tool for understanding galaxy formation and
evolution. Over the decades the field has made significant progress. It is now possible to …
