Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]

open access: yesThe 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 ...

Feedback and Brightest Cluster Galaxy Formation: ACS Observations of the Radio Galaxy TN J1338−1942 atz= 4.1 [PDF]

open access: bronze, 2005
We present deep optical imaging of the z = 4.1 radio galaxy TN J1338-1942, obtained using the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope, as well as ground-based near-infrared imaging data from the European Southern Observatory

Properties of the Brightest Cluster Galaxy and Its Host Cluster [PDF]

open access: bronzeThe 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]

open access: greenMonthly 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 ...

THE BRIGHTEST CLUSTER GALAXY IN A85: THE LARGEST CORE KNOWN SO FAR [PDF]

open access: bronze, 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]

open access: green, 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.

The Relationship Between Brightest Cluster Galaxy Star Formation and the Intracluster Medium in CLASH [PDF]

open access: hybrid, 2017
We study the nature of feedback mechanisms in the 11 CLASH brightest cluster galaxies (BCGs) that exhibit extended ultraviolet and nebular line emission features.

THE BLACK HOLE MASS IN THE BRIGHTEST CLUSTER GALAXY NGC 6086 [PDF]

open access: yes, 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 ...

OPTICAL IFU OBSERVATIONS OF THE BRIGHTEST CLUSTER GALAXY NGC 4696: THE CASE FOR A MINOR MERGER AND SHOCK-EXCITED FILAMENTS [PDF]

open access: yes, 2010
We present deep optical integral-field spectroscopic observations of the nearby (z ∼ 0.01) brightest cluster galaxy NGC 4696 in the core of the Centaurus Cluster, made with the Wide Field Spectrograph on the Australian National University 2.3 m telescope

Chandra Observations of Abell 2261 Brightest Cluster Galaxy, a Candidate Host to a Recoiling Black Hole [PDF]

open access: yes, 2020
We use Chandra X-ray observations to look for evidence of a recoiling black hole from the brightest cluster galaxy in Abell 2261 (A2261-BCG). A2261-BCG is a strong candidate for a recoiling black hole because of its large, flat stellar core, revealed by ...
