Brightest cluster galaxies: the centre can(not?) hold [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 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 ...

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 ...

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.

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 ...

A detection of wobbling brightest cluster galaxies within massive galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 A striking signal of dark matter beyond the standard model is the existence of cores in the centre of galaxy clusters. Recent simulations predict that a brightest cluster galaxy (BCG) inside a cored galaxy cluster will exhibit residual wobbling due to ...

The UV-upturn in brightest cluster galaxies [PDF]
Proceedings of the International Astronomical Union, 2010 This paper 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.

Stellar formation in Brightest Cluster Galaxies [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractWe study the interplay between stellar population of the Brightest Cluster Galaxies (BCG) and cluster global properties. We use X-ray properties from Chandra, ROSAT and ASCA observations and BCGs spectra from SDSS-DR6. Using STARLIGHT we determined the star formation history of the BCGs and look for relations with the intra-cluster gas ...

Structural analysis of brightest cluster galaxies in poor and rich clusters [PDF]
New Astronomy, 2022 Studying structural parameters of brightest cluster galaxies (BCGs) provides important clues to understand their formation and evolution. We present the results of the surface brightness profile fitting of 1685 brightest cluster galaxies (BCGs) drawn from the Canada-France-Hawaii Telescope Legacy Survey in the redshift range of $0.1 < z < 1.0 ...
