MAJOR CLUSTER MERGERS AND THE LOCATION OF THE BRIGHTEST CLUSTER GALAXY [PDF]

open access: yesThe Astrophysical Journal, 2014
Using a large N-body cosmological simulation combined with a subgrid treatment of galaxy formation, merging, and tidal destruction, we study the formation and evolution of the galaxy and cluster population in a comoving volume (100 Mpc)3 in a ΛCDM ...

Intracluster medium cooling, AGN feedback, and brightest cluster galaxy properties of galaxy groups - Five properties where groups differ from clusters [PDF]

open access: yes, 2014
Aims. We aim to investigate cool-core and non-cool-core properties of galaxy groups through X-ray data and compare them to the AGN radio output to understand the network of intracluster medium (ICM) cooling and feedback by supermassive black holes.

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE

open access: yesOdessa Astronomical Publications, 2014
The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.

Comparing Globular Cluster System Properties with Host Galaxy Environment

open access: yesThe Astrophysical Journal, 2023
We present Hubble Space Telescope photometry in the optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive elliptical galaxies.

A 1010 SOLAR MASS FLOW OF MOLECULAR GAS IN THE A1835 BRIGHTEST CLUSTER GALAXY [PDF]

open access: yes, 2013
We report ALMA Early Science observations of the A1835 brightest cluster galaxy (BCG) in the CO (3–2) and CO (1–0) emission lines. We detect 5 × 1010 M☉ of molecular gas within 10 kpc of the BCG. Its ensemble velocity profile width of ∼130 km s−1 FWHM is

A NOVEL APPROACH TO CONSTRAIN THE MASS RATIO OF MINOR MERGERS IN ELLIPTICAL GALAXIES: APPLICATION TO NGC 4889, THE BRIGHTEST CLUSTER GALAXY IN COMA [PDF]

open access: yesAstrophysical Journal, 2013
Minor mergers are thought to be important for the buildup and structural evolution of massive elliptical galaxies. In this work, we report the discovery of a system of four shell features in NGC 4889, one of the brightest members of the Coma cluster ...

Deep MOS Spectroscopy of NGC 1316 Globular Clusters

open access: yesGalaxies, 2017
The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

MASSIVE MOLECULAR GAS FLOWS IN THE A1664 BRIGHTEST CLUSTER GALAXY [PDF]

open access: yes, 2013
We report ALMA Early Science CO(1–0) and CO(3–2) observations of the brightest cluster galaxy (BCG) in A1664. The BCG contains 1.1 × 1010 M☉ of molecular gas divided roughly equally between two distinct velocity systems: one from −250 to +250 km s−1 ...

PS1-12sk IS A PECULIAR SUPERNOVA FROM A He-RICH PROGENITOR SYSTEM IN A BRIGHTEST CLUSTER GALAXY ENVIRONMENT [PDF]

open access: yes, 2013
We report on our discovery and observations of the Pan-STARRS1 supernova (SN) PS1-12sk, a transient with properties that indicate atypical star formation in its host galaxy cluster or pose a challenge to popular progenitor system models for this class of
