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 ...

Brightest cluster galaxies: the centre can(not?) hold [PDF]

open access: yesMonthly 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).

Intrinsic Shapes of Brightest Cluster Galaxies

open access: yesThe Astrophysical Journal, 2022
Abstract We discuss the statistical distribution of galaxy shapes and viewing angles under the assumption of triaxiality by deprojecting observed surface brightness profiles of 56 brightest cluster galaxies (BCGs) coming from a recently published large deep-photometry sample.

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

open access: yesAstrophysical 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,

Stellar Mass Growth of Brightest Cluster Galaxy Progenitors in COSMOS Since z ∼ 3 [PDF]

open access: yesAstrophysical Journal, 2019
We examine the role of environment on the in situ star formation (SF) hosted by the progenitors of the most massive galaxies in the present-day universe, the brightest cluster galaxies (BCGs), from z ∼ 3 to present in the COSMOS field.

THE LUMINOSITY PROFILES OF BRIGHTEST CLUSTER GALAXIES [PDF]

open access: yesThe 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 ...

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

open access: yesMonthly 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 ...
