MAJOR CLUSTER MERGERS AND THE LOCATION OF THE BRIGHTEST CLUSTER GALAXY [PDF]
Astrophysical Journal, 2014 Using a large N-body cosmological simulation combined with a subgrid treatment of galaxy formation, merging, and tidal destruction, we study the formation and evolution of the galaxy and cluster population in a comoving volume (100 Mpc)3 in a ΛCDM ...

A 13CO Detection in a Brightest Cluster Galaxy [PDF]
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.

THE BRIGHTEST CLUSTER GALAXY IN A85: THE LARGEST CORE KNOWN SO FAR [PDF]
Astrophysical Journal Letters, 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 ...

A BRIGHTEST CLUSTER GALAXY WITH AN EXTREMELY LARGE FLAT CORE [PDF]
Astrophysical Journal, 2012 Hubble Space Telescope images of the galaxy cluster A2261, obtained as part of the Cluster Lensing And Supernova survey with Hubble, show that the brightest galaxy in the cluster, A2261-BCG, has the largest core yet detected in any galaxy.

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

A Large Mass of H 2 in the Brightest Cluster Galaxy in Zwicky 3146 [PDF]
Astrophysical Journal, 2006 We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (LIR = 4 × 1011 L☉) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Zwicky 3146 (Z3146; z = 0.29).

The Formation of the Brightest Cluster Galaxy and Intracluster Light in Cosmological N-body Simulations with the Galaxy Replacement Technique [PDF]
Astrophysical Journal, 2022 We investigate the formation channels of the intracluster light (ICL) and the brightest cluster galaxy (BCG) in clusters at z = 0. For this, we perform multi-resolution cosmological N-body simulations using the “galaxy replacement technique.” We study ...

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,
