Detection of a Substantial Molecular Gas Reservoir in a Brightest Cluster Galaxy at z = 1.7 [PDF]
, 2017 We report the detection of CO(2–1) emission coincident with the brightest cluster galaxy (BCG) of the high-redshift galaxy cluster SpARCS1049+56, with the Redshift Search Receiver (RSR) on the Large Millimeter Telescope (LMT).

A Radio Relic and a Search for the Central Black Hole in the Abell 2261 Brightest Cluster Galaxy [PDF]
, 2017 We present VLA images and HST/STIS spectra of sources within the center of the brightest cluster galaxy (BCG) in Abell 2261. These observations were obtained to test the hypothesis that its extremely large, flat core reflects the ejection of its ...

The challenging task of determining star formation rates: the case of a massive stellar burst in the brightest cluster galaxy of Phoenix galaxy cluster [PDF]
, 2016 Star formation in galaxies at the center of cooling-flow galaxy clusters is an important phenomenon in the context of formation and evolution of massive galaxies in the Universe. Yet, star formation rates (SFRs) in such systems continue to be elusive. We

The HectoMAP Cluster Survey: Spectroscopically Identified Clusters and their Brightest Cluster Galaxies (BCGs) [PDF]
Astrophysical Journal, 2021 We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between brightest cluster galaxies (BCGs) and their host clusters.

Intrinsic Shapes of Brightest Cluster Galaxies
The 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.

Galactic cannibalism and CDM density profiles [PDF]
, 2004 Using N-body simulations we show that the process of formation of the brightest cluster galaxy through dissipationless galactic cannibalism can affect the inner cluster dark matter density profile.

Are Brightest Cluster Galaxies Special?
Research Notes of the AAS, 2023 A longstanding question when studying Brightest Cluster Galaxies (BCGs) and their evolution is whether their luminosities are statistical extremes of the luminosity distribution of other cluster member galaxies, or whether their luminosities follow a ...

Molecular gas in distant brightest cluster galaxies [PDF]
Astronomy & Astrophysics, 2020 The mechanisms governing the stellar mass assembly and star formation history of brightest cluster galaxies (BCGs) are still being debated. By means of new and archival molecular gas observations we investigate the role of dense megaparsec-scale environments in regulating the fueling of star formation in distant BCGs, through cosmic time.

Starbursting Brightest Cluster Galaxy: a Herschel view of the massive cluster MACS J1931.8-2634 [PDF]
, 2015 We investigate the dust-obscured star formation properties of the massive, X-ray selected galaxy cluster MACS J1931.8{2634 at z=0.352. Using far-infrared (FIR) imaging in the range 100-500 m obtained with the Herschel telescope, we extract 31 sources (2 )
