Clocking the formation of today’s largest galaxies: wide field integral spectroscopy of brightest cluster galaxies and their surroundings [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The formation and evolution of local brightest cluster galaxies (BCGs) is investigated by determining the stellar populations and dynamics from the galaxy core, through the outskirts and into the intracluster light (ICL).

Velocity Dispersions of Brightest Cluster Galaxies and Their Host Clusters [PDF]
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 ...

CLASH-VLT: The Inner Slope of the MACS J1206.2-0847 Dark Matter Density Profile
The Astrophysical Journal, 2023 The inner slope ( γ _DM ) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential.

Ellipticity of brightest cluster galaxies as tracer of halo orientation and weak-lensing mass bias [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Weak-lensing measurements of the masses of galaxy clusters are commonly based on the assumption of spherically symmetric density profiles. Yet, the cold dark matter model predicts the shapes of dark matter haloes to be triaxial.

The XMM Cluster Survey: The Stellar Mass Assembly of Fossil Galaxies [PDF]
, 2012 This paper presents both the result of a search for fossil systems (FSs) within the XMM Cluster Survey and the Sloan Digital Sky Survey and the results of a study of the stellar mass assembly and stellar populations of their fossil galaxies. In total, 17

The different growth pathways of Brightest Cluster Galaxies and the Intra-Cluster Light [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the growth pathways of brightest central galaxies (BCGs) and intracluster light (ICE) by means of a semi-analytic model. We assume that ICL forms by stellar stripping of satellite galaxies and violent processes during mergers, and implement two ...

LINEAR SUBSTRUCTURES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2019 We propose detailed scheme that is describing the morphology of linear substructures in galaxy clusters. Our base morphological scheme di- vides galaxy clusters using numerical criteria according the parameters: concentration to the cluster center, the ...

Galaxy Orientations in the Coma Cluster [PDF]
, 2007 We have examined the orientations of early-type galaxies in the Coma cluster to see whether the well-established tendency for brightest cluster galaxies to share the same major axis orientation as their host cluster also extends to the rest of the galaxy

Coordinated Assembly of Brightest Cluster Galaxies [PDF]
Astrophysical Journal, 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 ...
