A Large Mass of H_2 in the Brightest Cluster Galaxy in Zwicky 3146 [PDF]

, 2006
We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (L_(IR) = 4 × 10^(11) L_☉) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Zwicky 3146 (Z3146; z = 0.29).

Selecting Clusters and Protoclusters via Stellar Mass Density. II. Application to HSC-SSP Observations

The Astrophysical Journal
We present a selection of candidates of clusters and protoclusters of galaxies identified in the photometric data of the HSC-SSP Wide Public Data Release 3 (PDR3), spanning the redshift range 0.1 ≤ z ≤ 2. The selection method, detailed in Vicentin et al.,

JWST Photometry of Globular Cluster Populations in MACS0417.5−1154

The Astrophysical Journal
Deep JWST imaging of the massive galaxy cluster MACS0417.5−1154, at redshift z = 0.443, reveals a huge population of globular clusters (GCs) and ultracompact dwarfs (UCDs) primarily distributed around its single central giant brightest cluster galaxy ...

Black hole mass estimates in brightest cluster galaxies

, 2008
We present HST imaging and spectroscopic observations of three brightest cluster galaxies (BCGs), Abell 1836-BCG, Abell 2052-BCG, and Abell 3565-BCG, obtained with WFPC2, ACS, and STIS.

Detection of Compton Scattering in the Jet of 3C 84

The Astrophysical Journal Letters
3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low-frequency radio up to TeV γ -rays.

KINEMATICS OF 13 BRIGHTEST CLUSTER GALAXIES

, 1995
Velocity dispersion profiles and rotation curves have been determined for a sample of 13 brightest duster galaxies (BCGs) in order to study their internal stellar kinematics and investigate their relationship to ellipticals.
