SALT spectroscopic observations of galaxy clusters detected by ACT and a type II quasar hosted by a brightest cluster galaxy [PDF]
Monthly notices of the Royal Astronomical Society, 2014 We present Southern African Large Telescope (SALT) follow-up observations of seven massive clusters detected by the Atacama Cosmology Telescope (ACT) on the celestial equator using the Sunyaev-Zel’dovich (SZ) effect.

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

Mind the Gap: Tightening the Mass-Richness Relation with Magnitude Gaps [PDF]
, 2013 We investigate the potential to improve optical tracers of cluster mass by exploiting measurements of the magnitude gap, m12, defined as the difference between the r-band absolute magnitude of the two brightest cluster members.

Coordinated Assembly of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal Letters, 2018 Abstract Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of Abell 3827 at z ∼ 0.1, including five-nucleus galaxies involved in a BCG assembly.

Intracluster medium cooling, AGN feedback, and brightest cluster galaxy properties of galaxy groups - Five properties where groups differ from clusters [PDF]
, 2014 Aims. We aim to investigate cool-core and non-cool-core properties of galaxy groups through X-ray data and compare them to the AGN radio output to understand the network of intracluster medium (ICM) cooling and feedback by supermassive black holes.

Witnessing the formation of a brightest cluster galaxy at z>2 [PDF]
, 2006 We present deep observations taken with the HST Advanced Camera for Surveys of the central massive galaxy in a forming cluster at z=2.2. The galaxy hosting the powerful radio source MRC 1138-262 is associated with one of the most extensive merger systems
