An Infrared Survey of Brightest Cluster Galaxies. II. Why are Some Brightest Cluster Galaxies Forming Stars? [PDF]

The Astrophysical Journal, 2008
Quillen et al.(2007) presented an imaging survey with the {\it Spitzer Space Telescope} of 62 brightest cluster galaxies with optical line emission located in the cores of X-ray luminous clusters. They found that at least half of these sources have signs of excess infrared emission. Here we discuss the nature of the IR emission and its implications for

Are Brightest Cluster Galaxies Special?

Research Notes of the AAS, 2023
Abstract A longstanding question when studying Brightest Cluster Galaxies (BCGs) and their evolution is whether their luminosities are statistical extremes of the luminosity distribution of other cluster member galaxies, or whether their luminosities follow a different,“special” distribution.

Brightest Cluster Galaxies in Strongly-Lensing Galaxy Clusters and Richness- and Redshift-Matched Samples [PDF]

, 2022
We present a statistical analysis of 588 strongly-lensing galaxy clusters and groups, selected from publicly-available imaging sky surveys primarily by the COOL-LAMPS (ChicagO Optically selected strong Lenses — Located At the Margins of Public Surveys ...

Are Dumbbell Brightest Cluster Members Signposts to Galaxy Cluster Activity? [PDF]

, 2008
We assemble a sample of galaxy clusters whose brightest members are dumbbell galaxies and compare them with a control sample in order to investigate if they are the result of recent mergers.

STAGES:the Space Telescope A901/2 Galaxy Evolution Survey [PDF]

, 2008
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range of environments and luminosity.

The Evolution of AGN Activity in Brightest Cluster Galaxies

The Astronomical Journal, 2022
Abstract We present the results of an analysis of Wide-field Infrared Survey Explorer (WISE) observations of the full 2500 deg2 South Pole Telescope (SPT)-Sunyaev–Zel’dovich cluster sample. We describe a process for identifying active galactic nuclei (AGN) in brightest cluster galaxies (BCGs) based on WISE mid-IR color and redshift ...

X-ray emission in the Abell 2597 Brightest Cluster Galaxy [PDF]

, 2012
0.5-7 keV X-ray surface brightness map of the central brightest cluster galaxy in Abell 2597. The X-ray emission has been smoothed with an adaptive gaussian kernel, and surface brightness isocontours have been overlaid in black. East is left, North is up.

EVOLUTIONARY EFFECTS ON BRIGHTEST CLUSTER GALAXY (BCG) DETECTIONS IN THE CFHTLS-DEEP FIELDS [PDF]

, 2021
Brightest cluster galaxies (BCGs) are the most massive and most luminous galaxies in the universe. These galaxies dominate galaxy clusters and lie at the top of the potential well of clusters.
