The faint light in groups and clusters of galaxies [PDF]
Nature Astronomy, 2022 The diffuse light that spreads through groups and clusters of galaxies is made of free-floating stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds important clues for understanding the evolution of these large ...

Lost but not forgotten: Intracluster light in galaxy groups and clusters [PDF]
, 2017 With Hubble Space Telescope imaging, we investigate the progenitor population and formation mechanisms of the intracluster light (ICL) for 23 galaxy groups and clusters ranging from 3$\times10^{13} 10^{11.6}$ M$_\odot$), while by 100 kpc this colour is ...

Constraints on the Optical Depth of Galaxy Groups and Clusters [PDF]
, 2016 Future data from galaxy redshift surveys, combined with high-resolutions maps of the cosmic microwave background, will enable measurements of the pairwise kinematic Sunyaev–Zel’dovich (kSZ) signal with unprecedented statistical significance.

Iron in galaxy groups and clusters: confronting galaxy evolution models with a newly homogenized data set [PDF]
, 2016 We present an analysis of the iron abundance in the hot gas surrounding galaxy groups and clusters. To do this, we first compile and homogenize a large data set of 79 low-redshift (z = 0.03) systems (159 individual measurements) from the literature.

Towards a realistic population of simulated galaxy groups and clusters [PDF]
, 2013 We present a new suite of large-volume cosmological hydrodynamical simulations called cosmo-OWLS. They form an extension to the OverWhelmingly Large Simulations (OWLS) project, and have been designed to help improve our understanding of cluster ...

The Astrophysical Journal, 2023 We investigate the fraction of quenched satellite galaxies in host galaxy groups and clusters using TNG300 in the IllustrisTNG cosmological magnetohydrodynamical simulations.

Integrated HI emission in galaxy groups and clusters [PDF]
, 2017 The integrated HI emission from hierarchical structures such as groups and clusters of galaxies can be detected by FAST at intermediate redshifts. Here we propose to use FAST to study the evolution of the global HI content of clusters and groups over ...

Scaling Properties of Galaxy Groups
Universe, 2021 Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...

Galaxy evolution in groups and clusters: satellite star formation histories and quenching time-scales in a hierarchical Universe [PDF]
, 2012 Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFR) and lie on the red-sequence than central (field) galaxies.

Galaxies, 2021 Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found
