Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]
The Astrophysical Journal, 2018 The orientations of brightest cluster galaxies (BCGs) and their host clusters tend to be aligned, but the mechanism driving this is not clear. To probe the role of cluster mergers in this process, we quantify alignments of 38 BCGs in 22 clusters ...

The Origin of the Brightest Cluster Galaxies [PDF]
The Astrophysical Journal, 1998 Most clusters and groups of galaxies contain a giant elliptical galaxy in their centres which far outshines and outweighs normal ellipticals. The origin of these brightest cluster galaxies is intimately related to the collapse and formation of the cluster. Using an N-body simulation of a cluster of galaxies in a hierarchical cosmological model, we show

A 13CO Detection in a Brightest Cluster Galaxy [PDF]
The Astrophysical Journal, 2017 We present ALMA Cycle 4 observations of CO(1-0), CO(3-2), and 13CO(3-2) line emission in the brightest cluster galaxy (BCG) of RXJ0821+0752. This is one of the first detections of 13CO line emission in a galaxy 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, merging, and tidal destruction, we study the formation and evolution of the galaxy and cluster population in a comoving volume (100 Mpc)3 in a ΛCDM ...

Brightest Cluster Galaxy Profile Shapes [PDF]
The Astrophysical Journal, 1996 We model the surface brightness profiles of a sample of 119 Abell Brightest Cluster Galaxies (BCG), finding a generalised deVaucouleurs R^{1/n} law, where n is a free parameter, to be appropriate.

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. This

Deep MOS Spectroscopy of NGC 1316 Globular Clusters [PDF]
Galaxies, 2017 The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

THE BLACK HOLE MASS IN THE BRIGHTEST CLUSTER GALAXY NGC 6086 [PDF]
, 2010 We present the first direct measurement of the central black hole mass, M•, in NGC 6086, the Brightest Cluster Galaxy (BCG) in A2162. Our investigation demonstrates for the first time that stellar-dynamical measurements of M• in BCGs are possible beyond ...
