Constraints on the Size Evolution of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal, 2002 We measure the luminosity profiles of 16 brightest cluster galaxies (BCGs) at $0.4 < z < 0.8$ using high resolution F160W NICMOS and F814W WFPC2 HST imaging. The heterogeneous sample is drawn from a variety of surveys: seven from clusters in the Einstein Medium Sensitivity Survey, five from the Las Campanas Distant Cluster Survey and its northern

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 ...

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.

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.

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

The Black Hole Mass in Brightest Cluster Galaxy NGC 6086 [PDF]
, 2010 We present the first direct measurement of the central black hole mass, M_BH, in NGC 6086, the Brightest Cluster Galaxy (BCG) in Abell 2162. Our investigation demonstrates for the first time that stellar dynamical measurements of M_BH in BCGs are ...

Optical IFU Observations of the Brightest Cluster Galaxy NGC 4696: The Case for a Minor Merger and Shock-excited Filaments [PDF]
, 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 (WiFeS) on the ANU 2.3m telescope at Siding Spring ...

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.
