A ¹³CO Detection in a Brightest Cluster Galaxy [PDF]

The Astrophysical Journal, 2017
Abstract We present ALMA Cycle 4 observations of CO(1-0), CO(3-2), and 13CO(3-2) line emission in the brightest cluster galaxy (BCG) of RXJ0821+0752. This is one of the first detections of 13CO line emission in a galaxy cluster. Half of the CO(3-2) line emission originates from two clumps of molecular gas that are spatially offset from ...

The Galaxy Population of Cluster RXJ0848+4453 at z=1.27 [PDF]

, 2001
We present a study of the galaxy population in the cluster RXJ0848+4453 at z=1.27, using deep HST NICMOS and WFPC2 images. We morphologically classify all galaxies to K_s=20.6 that are covered by the HST imaging, and determine photometric redshifts using

How special are brightest group and cluster galaxies? [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
Abstract We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster ...

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE

Odessa 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.

An Infrared Survey of Brightest Cluster Galaxies. II. Why are Some Brightest Cluster Galaxies Forming Stars? [PDF]

The Astrophysical Journal, 2008
Quillen et al.(2007) presented an imaging survey with the {\it Spitzer Space Telescope} of 62 brightest cluster galaxies with optical line emission located in the cores of X-ray luminous clusters. They found that at least half of these sources have signs of excess infrared emission. Here we discuss the nature of the IR emission and its implications for

THE DETERMINATION OF THE MORPHOLOGICAL TYPES OF GALAXY CLUSTERS USING CLUSTER CARTOGRAPHY

Odessa Astronomical Publications, 2016
We discuss the possibility of using the Cluster Cartography set for the determined the morphological types of galaxy clusters. The applied morphological scheme was proposed by Panko (2013).

The stellar content of brightest cluster galaxies [PDF]

, 2000
We present near-infrared K-band spectroscopy of 21 elliptical or cD Brightest Cluster Galaxies (BCGs), for which we have measured the strength of the 2.293 micron CO stellar absorption feature.

The ROSAT Brightest Cluster Sample — III. Optical spectra of the central cluster galaxies [PDF]

, 1999
We present new spectra of dominant galaxies in X-ray selected clusters of galaxies, which combine with our previously published spectra to form a sample of 256 dominant galaxies in 215 clusters.

Evolution of brightest cluster galaxies in X ray clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2002
A recent paper (Burke, Collins & Mann 2000) presents the analysis of the K-band Hubble diagram of 76 brightest cluster galaxies (BCGs) in X-ray clusters and shows that the properties of BCGs depend on the X-ray luminosity (Lx) of their host clusters.
