The Angular Momentum of Brightest Cluster Galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractMassive Brightest Cluster Galaxies (BCGs) are observed to have a range of angular momenta, suggesting a variety of merging histories.

The XMM Cluster Survey: The Stellar Mass Assembly of Fossil Galaxies [PDF]
, 2012 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 assembly and stellar populations of their fossil galaxies. In total, 17

The different growth pathways of Brightest Cluster Galaxies and the Intra-Cluster Light [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the growth pathways of brightest central galaxies (BCGs) and intracluster light (ICE) by means of a semi-analytic model. We assume that ICL forms by stellar stripping of satellite galaxies and violent processes during mergers, and implement two ...

LINEAR SUBSTRUCTURES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2019 We propose detailed scheme that is describing the morphology of linear substructures in galaxy clusters. Our base morphological scheme di- vides galaxy clusters using numerical criteria according the parameters: concentration to the cluster center, the ...

Galaxy Orientations in the Coma Cluster [PDF]
, 2007 We have examined the orientations of early-type galaxies in the Coma cluster to see whether the well-established tendency for brightest cluster galaxies to share the same major axis orientation as their host cluster also extends to the rest of the galaxy

The ROSAT Brightest Cluster Sample — III. Optical spectra of the central cluster galaxies [PDF]
, 1999 We present new spectra of dominant galaxies in X-ray selected clusters of galaxies, which combine with our previously published spectra to form a sample of 256 dominant galaxies in 215 clusters.

The Galaxy Population of Cluster RXJ0848+4453 at z=1.27 [PDF]
, 2001 We present a study of the galaxy population in the cluster RXJ0848+4453 at z=1.27, using deep HST NICMOS and WFPC2 images. We morphologically classify all galaxies to K_s=20.6 that are covered by the HST imaging, and determine photometric redshifts using

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE
Odessa Astronomical Publications, 2014 The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.

Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]
The Astrophysical Journal, 2019 Abstract The orientations of brightest cluster galaxies (BCGs) and their host clusters tend to be aligned, but the mechanism driving this is not clear. To probe the role of cluster mergers in this process, we quantify alignments of 38 BCGs in 22 clusters undergoing major mergers (up to ∼1 Gyr after first pericenter).
