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 ...

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 ...

The hierarchical formation of the brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We use semi-analytic techniques to study the formation and evolution of brightest cluster galaxies (BCGs). We show the extreme hierarchical nature of these objects and discuss the limitations of simple ways to capture their evolution.

The Origin of the Brightest Cluster Galaxies [PDF]
The Astrophysical Journal, 1997 Most clusters and groups of galaxies contain a giant elliptical galaxy in their centres which far outshines and outweighs normal ellipticals. The origin of these brightest cluster galaxies is intimately related to the collapse and formation of the ...

Coordinated Assembly of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal Letters, 2018 Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of Abell 3827 at z ∼ 0.1, including five-nucleus galaxies involved in a BCG ...

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.

The UV-upturn in brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 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.

Velocity Dispersions of Brightest Cluster Galaxies and Their Host Clusters [PDF]
The Astrophysical Journal, 2019 We explore connections between brightest cluster galaxies (BCGs) and their host clusters. We first construct a HeCS-omnibus cluster sample including 227 galaxy clusters within 0.02 < z < 0.30; the total number of spectroscopic members from MMT/Hectospec ...

Structure of Brightest Cluster Galaxies and Intracluster Light [PDF]
The Astrophysical Journal Supplement Series, 2019 Observations of 170 local (z ≲ 0.08) galaxy clusters in the northern hemisphere have been obtained with the Wendelstein Telescope Wide Field Imager (WWFI).

Dynamics and Shape of Brightest Cluster Galaxies [PDF]
, 2006 We identified Brightest Cluster Members (BCM) on DSS images of 1083 Abell clusters, derived their individual and host cluster redshifts from literature and determined the BCM ellipticity.
