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

Quenching of satellite galaxies at the outskirts of galaxy clusters [PDF]
, 2016 We find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{\rm shock}\sim(2 - 3) R_{\rm vir}$, where $R_{\rm vir}$ is the standard virial

ФОРМЫ ТРЕХКОМПОНЕНТНЫХ СВЕРХСКОПЛЕНИЙ ГАЛАКТИК
Odessa Astronomical Publications, 2011 We analyzed the shapes of galaxy superclusters, contains only 3 galaxy clusters. The superclusters were found using PF Catalogue Galaxy Clusters and Groups covering 5000 square degrees as input data.

Galaxy Clusters in the Context of Superfluid Dark Matter [PDF]
, 2016 It has recently been proposed, by assuming that dark matter is a superfluid, that MOND-like effects can be achieved on small scales whilst preserving the success of $\Lambda$CDM on large scales. Here we aim to provide the first set of spherical models of

Unravelling the origin of large-scale magnetic fields in galaxy clusters and beyond through Faraday Rotation Measures with the SKA [PDF]
, 2014 We investigate the possibility for the SKA to detect and study the magnetic fields in galaxy clusters and in the less dense environments surrounding them using Faraday Rotation Measures.

LoCuSS: weak-lensing mass calibration of galaxy clusters [PDF]
, 2015 We present weak-lensing mass measurements of 50 X-ray luminous galaxy clusters at $0.15\le z\le0.3$, based on uniform high quality observations with Suprime-Cam mounted on the 8.2-m Subaru telescope.

The Astrophysical Journal, 2023 A fraction of merging galaxy clusters host diffuse radio emission in their central region, termed a giant radio halo (GRH). The most promising mechanism of GRHs is the reacceleration of nonthermal electrons and positrons by merger-induced turbulence ...

ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY
Odessa Astronomical Publications, 2007 We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

Occurrence of radio halos in galaxy clusters - Insight from a mass-selected sample [PDF]
, 2015 Giant radio halos (RH) are diffuse Mpc-scale synchrotron sources detected in a fraction of massive and merging galaxy clusters. An unbiased study of the statistical properties of RHs is crucial to constrain their origin and evolution.
