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 ...

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.

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

, 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.

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

, 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 ...

Deep and narrow CO absorption revealing molecular clouds in the Hydra-A brightest cluster galaxy [PDF]

Monthly notices of the Royal Astronomical Society, 2019
Active galactic nuclei play a crucial role in the accretion and ejection of gas in galaxies. Although their outflows are well studied, finding direct evidence of accretion has proved very difficult and has so far been done for very few sources.

The Dust and Molecular Gas in the Brightest Cluster Galaxy in MACS 1931.8-2635 [PDF]

Astrophysical Journal, 2019
We present new Atacama Large Millimeter Array observations of the molecular gas and far-infrared continuum around the brightest cluster galaxy (BCG) in the cool-core cluster MACS 1931.8-2635. Our observations reveal (1.9 ± 0.3) × 1010 M⊙ of molecular gas,

A radio halo surrounding the Brightest Cluster Galaxy in RXCJ0232.2–4420: a mini-halo in transition? [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2019
Diffuse radio sources associated with the intra-cluster medium are direct probes of the cosmic ray electrons and magnetic fields. We report the discovery of a diffuse radio source in the galaxy cluster RXCJ0232.2–4420 (SPT-CL J0232–4421, z = 0.2836 ...
