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.

The Brightest UV-selected Galaxies in Protoclusters at z ∼ 4: Ancestors of Brightest Cluster Galaxies? [PDF]
The Astrophysical Journal, 2019 Abstract We present the results of a survey of the brightest UV-selected galaxies in protoclusters. These proto-brightest cluster galaxy (proto-BCG) candidates are drawn from 179 overdense regions of g-dropout galaxies at z ∼ 4 from the Hyper Suprime-Cam Subaru Strategic Program identified previously as good protocluster candidates.

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 ...

A detection of wobbling brightest cluster galaxies within massive galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 A striking signal of dark matter beyond the standard model is the existence of cores in the centre of galaxy clusters. Recent simulations predict that a Brightest Cluster Galaxy (BCG) inside a cored galaxy cluster will exhibit residual wobbling due to previous major mergers, long after the relaxation of the overall cluster.

MAJOR CLUSTER MERGERS AND THE LOCATION OF THE BRIGHTEST CLUSTER GALAXY [PDF]
The Astrophysical Journal, 2014 Using a large N-body cosmological simulation combined with a subgrid treatment of galaxy formation, we study the formation and evolution of the galaxy and cluster population in a comoving volume (100 Mpc)^3 in a LCDM universe. At z = 0, our computational volume contains 1788 clusters with mass M_cl > 1.1x10^12 Msun, including 18 massive clusters ...

The shapes of brightest cluster galaxies
The Astrophysical Journal, 1993 The mean isophotal axis ratios are computed for a complete sample of 119 brightest cluster galaxies (BCGs) in Abell clusters. The cumulative distribution function F(q) of axis ratios for the BCGs differs from F(q) for a sample of ordinary elliptical galaxies at only the P=0.14 probability level, as measured by a Kolmogorov Smirnov test.
