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.

Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]
The Astrophysical Journal, 2019 Abstract 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 undergoing major mergers (up to ∼1 Gyr after first pericenter).

How special are brightest group and cluster galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Abstract We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster ...

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.

Ionized nebulae surrounding brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We present IFU observations of six emission-line nebulae that surround the central galaxy of cool core clusters. Qualitatively similar nebulae are observed in cool core clusters even when the dynamics and possibly formation and excitation source are different.

Precision Modeling of JWST's First Cluster Lens SMACS J0723.3–7327
The Astrophysical Journal, 2023 Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens model for the massive galaxy cluster SMACS J0723.3−7323 (SMACS J0723; z = 0.388) that significantly improves upon earlier work.
