The Formation of the Brightest Cluster Galaxy and Intracluster Light in Cosmological N-body Simulations with the Galaxy Replacement Technique [PDF]
The Astrophysical Journal, 2023 We investigate the formation channels of the intracluster light (ICL) and the brightest cluster galaxy (BCG) in clusters at z = 0. For this, we perform multi-resolution cosmological N -body simulations using the “galaxy replacement technique.” We study ...

Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]
The Astrophysical Journal, 2018 The orientations of brightest cluster galaxies (BCGs) and their host clusters tend to be aligned, but the mechanism driving this is not clear. To probe the role of cluster mergers in this process, we quantify alignments of 38 BCGs in 22 clusters ...

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 ...

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 Galaxy Profile Shapes [PDF]
The Astrophysical Journal, 1996 We model the surface brightness profiles of a sample of 119 Abell Brightest Cluster Galaxies (BCG), finding a generalised deVaucouleurs R^{1/n} law, where n is a free parameter, to be appropriate.

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).

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.

Chandra Observations of Abell 2261 Brightest Cluster Galaxy, a Candidate Host to a Recoiling Black Hole [PDF]
, 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 ...

Deep and narrow CO absorption revealing molecular clouds in the Hydra-A brightest cluster galaxy [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Active galactic nuclei play a crucial role in the accretion and ejection of gas in galaxies. Although their outflows are well studied, finding direct evidence of accretion has proved very difficult and has so far been done for very few sources.

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