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.

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 ...

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 ...

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.

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 CLUSTER GALAXY IN A85: THE LARGEST CORE KNOWN SO FAR [PDF]
, 2014 We have found that the brightest cluster galaxy (BCG) in A85, Holm 15A, displays the largest core known so far. Its cusp radius, rγ = 4.57 ± 0.06 kpc (4.″26 ± 0.″06), is more than 18 times larger than the mean for BCGs and ≳ 1 kpc larger than A2261-BCG ...

Revisiting Brightest Cluster Galaxy Evolution with the Las Campanas Distant Cluster Survey [PDF]
, 2002 We investigate the influence of environment on brightest cluster galaxy (BCG) evolution using a sample of 63 clusters at 0.3 ≤ z ≤ 0.9 drawn primarily from the Las Campanas Distant Cluster Survey and follow-up V, I, and K' photometry.
