Intrinsic shapes of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal, 2022 We discuss the statistical distribution of galaxy shapes and viewing angles under the assumption of triaxiality by deprojecting observed Surface Brightness (SB) profiles of 56 Brightest Cluster Galaxies coming from a recently published large deep ...

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

The Brightest UV-selected Galaxies in Protoclusters at z ∼ 4: Ancestors of Brightest Cluster Galaxies? [PDF]
The Astrophysical Journal, 2019 We present the results of a survey of the brightest UV-selected galaxies in protoclusters. These proto-brightest cluster galaxy (proto-BCG) candidates are drawn from 179 overdense regions of g-dropout galaxies at z ∼ 4 from the Hyper Suprime-Cam Subaru ...

Alignment of brightest cluster galaxies with their host clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We examine the alignment between brightest cluster galaxies (BCGs) and their host clusters in a sample of 7031 clusters with 0.08 0.65 mag brighter than the mean of the second- and third-ranked galaxies) show stronger alignment than do clusters with ...

AGN in Brightest Cluster Galaxies
, 2018 We present a systematic investigation of the nuclear activity in Brighest Cluster Galaxies through cosmic epochs. By combining X-ray, Radio, optical and IR data, we constrain the origin of the feeding gas and the accretion regime, as well as the ...

Brightest cluster galaxies as probes of galaxy formation
, 2016 Brightest group and cluster galaxies are the most massive galaxies in the Universe and reside at the centres of galaxy clusters. These galaxies push galaxy formation and evolution models to their limits, providing a strong test to our current paradigm of

The Astrophysical JournalWe use the L-GALAXIES semianalytic model to investigate the evolution of brightest cluster galaxies (BCGs) found in clusters at z ∼ 0. BCGs are typically located in the central region of galaxy clusters, near the bottom of the potential well, exposing ...

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 ...

GALAXY CLUSTERS AT HIGH REDSHIFT AND EVOLUTION OF BRIGHTEST CLUSTER GALAXIES [PDF]
The Astrophysical Journal, 2011 Identification of high redshift clusters is important for studies of cosmology and cluster evolution. Using photometric redshifts of galaxies, we identify 631 clusters from the Canada-France-Hawaii Telescope (CFHT) Wide field, 202 clusters from the CHFT Deep field, 187 clusters from the Cosmic Evolution Survey (COSMOS) and 737 clusters from the Spitzer
