The HectoMAP Cluster Survey: Spectroscopically Identified Clusters and their Brightest Cluster Galaxies (BCGs) [PDF]
Astrophysical Journal, 2021 We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between brightest cluster galaxies (BCGs) and their host clusters.

Are Brightest Cluster Galaxies Special?
Research Notes of the AAS, 2023 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 ...

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.

Shapes and alignments of dark matter haloes and their brightest cluster galaxies in 39 strong lensing clusters [PDF]
, 2020 We study shapes and alignments of 45 dark matter (DM) haloes and their brightest cluster galaxies (BCGs) using a sample of 39 massive clusters from Hubble Frontier Field (HFF), Cluster Lensing And Supernova survey with Hubble (CLASH), and Reionization ...

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 ...

The growth of brightest cluster galaxies and intracluster light over the past 10 billion years [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We constrain the evolution of the brightest cluster galaxy plus intracluster light (BCG + ICL) using an ensemble of 42 galaxy groups and clusters that span redshifts of z = 0.05−1.75 and masses of M500,c= 2 × 1013−1015 M⊙.

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

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.
