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,

Brightest cluster galaxies: the centre can(not?) hold [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the centroid of the X-ray gas distribution and/or show peculiar velocities (they are not at rest with respect to the cluster mean).

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 ...

A Photometric Survey of Globular Cluster Systems in Brightest Cluster Galaxies [PDF]
Astrophysical Journal Supplement Series, 2022 Hubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies and their distances

First Results on the Cluster Galaxy Population from the Subaru Hyper Suprime-Cam Survey. III. Brightest Cluster Galaxies, Stellar Mass Distribution, and Active Galaxies [PDF]
, 2017 The unprecedented depth and area surveyed by the Subaru Strategic Program with the Hyper Suprime-Cam (HSC-SSP) have enabled us to construct and publish the largest distant cluster sample out to to date.

The Angular Momentum of Brightest Cluster Galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractMassive Brightest Cluster Galaxies (BCGs) are observed to have a range of angular momenta, suggesting a variety of merging histories.

THE LUMINOSITY PROFILES OF BRIGHTEST CLUSTER GALAXIES [PDF]
The Astrophysical Journal Supplement Series, 2011 (Abridged) We have derived detailed R band luminosity profiles and structural parameters for a total of 430 brightest cluster galaxies (BCGs), down to a limiting surface brightness of 24.5 mag/arcsec^2. Light profiles were initially fitted with a Sersic's R^(1/n) model, but we found that 205 (~48) BCGs require a double component model to accurately ...

The ultraviolet upturn in brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 AbstractThis study is part of a series devoted to the investigation of a large sample of brightest cluster galaxies (BCGs), their properties and the relationships between these and the properties of the host clusters. In this paper, we compare the stellar population properties derived from high signal-to-noise, optical long-slit spectra with the GALEX ...
