Structure of Brightest Cluster Galaxies and Intracluster Light [PDF]
The Astrophysical Journal Supplement Series, 2019 Observations of 170 local (z ≲ 0.08) galaxy clusters in the northern hemisphere have been obtained with the Wendelstein Telescope Wide Field Imager (WWFI).

BRIGHTEST CLUSTER GALAXIES AT THE PRESENT EPOCH [PDF]
The Astrophysical Journal, 2014 We have obtained photometry and spectroscopy of 433 z ⩽ 0.08 brightest cluster galaxies (BCGs) in a full-sky survey of Abell clusters to construct a BCG sample suitable for probing deviations from the local Hubble flow. The BCG Hubble diagram over 0 < z <

Constraints on the Size Evolution of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal, 2002 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 Medium Sensitivity Survey, five from the Las Campanas Distant Cluster Survey and its northern

Constraining cold accretion on to supermassive black holes: molecular gas in the cores of eight brightest cluster galaxies revealed by joint CO and CN absorption [PDF]
Monthly notices of the Royal Astronomical Society, 2019 To advance our understanding of the fuelling and feedback processes which power the Universe’s most massive black holes, we require a significant increase in our knowledge of the molecular gas which exists in their immediate surroundings.

Properties of the Brightest Cluster Galaxy and Its Host Cluster [PDF]
The Astrophysical Journal, 2003 We investigate the relation between the properties of Brightest Cluster Galaxies (BCGs) and those of their host clusters. To quantify the properties of cluster hot gas, we employ the parameter $Z$ of the fundamental plane of X-ray clusters. It is found that the offset of the BCG from the peak of cluster X-ray emission is larger for smaller $Z$ clusters.

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 ...

Radio luminosity function of brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 By cross-matching the currently largest optical catalog of galaxy clusters and the NVSS radio survey database, we obtain the largest complete sample of brightest cluster galaxies (BCGs) in the redshift range of 0 ...

AGN in Brightest Cluster Galaxies
, 2018 We present a systematic investigation of the nuclear activity in Brighest Cluster Galaxies through cosmic epochs. By combining X-ray, Radio, optical and IR data, we constrain the origin of the feeding gas and the accretion regime, as well as the feedback processes affecting the surrounding Intra Cluster Medium and star formation events in the BCGs ...

A multiwavelength photometric census of AGN and star formation activity in the brightest cluster galaxies of X-ray selected clusters [PDF]
, 2016 Despite their reputation as being 'red and dead', the unique environment inhabited by brightest cluster galaxies (BCGs) can often lead to a self-regulated feedback cycle between radiatively cooling intracluster gas and star formation and active galactic ...

A comprehensive study of the radio properties of brightest cluster galaxies [PDF]
, 2015 We examine the radio properties of the brightest cluster galaxies (BCGs) in a large sample of X-ray selected galaxy clusters comprising the Brightest Cluster Sample (BCS), the extended BCS and ROSAT-ESO Flux Limited X-ray cluster catalogues.
