We review the formation and evolution of fossil groups and clusters from both the theoretical
and the observational points of view. In the optical band, these systems are dominated by …

We construct mock catalogues of galaxy groups using subhalo abundance matching
(SHAM) and undertake several new tests of the SHAM prescription for the galaxy–dark …

Galaxy clusters contain a diffuse stellar component outside the cluster's galaxies, which is
observed as faint intracluster light (ICL). Using Gemini/GMOS-N deep imaging and …

There have been a number of studies dedicated to identification of fossil galaxy groups,
arguably groups with a relatively old formation epoch. Most of such studies identify fossil …

We characterize the luminosity distribution, halo-mass dependence, and redshift evolution of
red galaxies in galaxy clusters using the SDSS Data Release 8 redMaPPer cluster sample …

This paper presents both the result of a search for fossil systems (FSs) within the XMM
Cluster Survey and the Sloan Digital Sky Survey and the results of a study of the stellar mass …

We examine the statistical properties of the brightest group galaxies (BGGs) by using a
complete spectroscopic sample of groups/clusters of galaxies selected from the Data …

We present a catalog of 129 X-ray galaxy groups, covering a redshift range 0.04< z< 1.23,
selected in the~ 3 deg 2 part of the CFHTLS W1 field overlapping XMM observations …

Context. In nature we observe galaxy aggregations that span a wide range of magnitude
gaps between the two first-ranked galaxies of a system (Δm 12). Thus, there are systems …

Context. Fossil groups (FG) are expected to be the final product of galaxy merging within
galaxy groups. In simulations, they are predicted to assemble their mass at high redshift …
