The stellar content of brightest cluster galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2000
We present near-infrared K-band spectroscopy of 21 elliptical or cD Brightest Cluster Galaxies (BCGs), for which we have measured the strength of the 2.293 micron CO stellar absorption feature.

Alignment of Brightest Cluster Galaxies with their Host Clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We examine the alignment between Brightest Cluster Galaxies (BCGs) and their host clusters in a sample of 7031 clusters with 0 ...

Constraints On the Size Evolution of Brightest Cluster Galaxies [PDF]

The Astrophysical Journal, 2001
We measure the luminosity profiles of 16 brightest cluster galaxies (BCGs) at $0.4 < z < 0.8$ using high resolution F160W NICMOS and F814W WFPC2 HST imaging. The heterogeneous sample is drawn from a variety of surveys: seven from clusters in the Einstein

A New Test of the Statistical Nature of the Brightest Cluster Galaxies [PDF]

, 2010
A novel statistic is proposed to examine the hypothesis that all cluster galaxies are drawn from the same luminosity distribution (LD). In such a "statistical model" of galaxy LD, the brightest cluster galaxies (BCGs) are simply the statistical extreme ...

Atmospheric Pressure and Molecular Cloud Formation in Early-type Galaxies

The Astrophysical Journal, 2023
A strong correlation between atmospheric pressure and molecular gas mass is found in central cluster galaxies and early-type galaxies. This trend and a similar trend with atmospheric gas density would naturally arise if the molecular clouds condensed ...

A Photometric Survey of Globular Cluster Systems in Brightest Cluster Galaxies

The Astrophysical Journal Supplement Series, 2023
Hubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies and their distances

CLASH-VLT: The Inner Slope of the MACS J1206.2-0847 Dark Matter Density Profile

The Astrophysical Journal, 2023
The inner slope ( γ _DM ) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential.

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

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
