The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]
, 1997 A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these ...

The Astrophysical Journal, 2023 We present the first systematic study of the detailed shapes of the line-of-sight velocity distributions (LOSVDs) in nine massive early-type galaxies (ETGs) using the novel nonparametric modeling code WINGFIT.

STAR FORMATION IN INTERMEDIATE REDSHIFT 0.2 < z < 0.7 BRIGHTEST CLUSTER GALAXIES [PDF]
, 2016 We present a multi-wavelength photometric and spectroscopic study of 42 Brightest Cluster Galaxies (BCGs) in two samples of galaxy clusters chosen for a gravitational lensing study. The study’s initial sample combines 25 BCGs from the Cluster Lensing and

Galaxies, 2021 Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found

Exploring the progenitors of brightest cluster galaxies at z ∼ 2 [PDF]
, 2016 We present a new method for tracing the evolution of brightest cluster galaxies (BCGs) from z ∼ 2 to z ∼ 0. We conclude on the basis of semi-analytical models that the best method to select BCG progenitors at z ∼ 2 is a hybrid environmental density and ...

Dynamics and Shape of Brightest Cluster Galaxies
, 2006 We identified Brightest Cluster Members (BCM) on DSS images of 1083 Abell clusters, derived their individual and host cluster redshifts from literature and determined the BCM ellipticity.

About the linearity of the color-magnitude relation of early-type galaxies in the Virgo cluster [PDF]
, 2013 We revisit the color-magnitude relation (CMR) of the Virgo cluster early-type galaxies in order to explore its alleged non-linearity. To this aim, we reanalyze the relation already published from data obtained within the ACS Virgo Cluster Survey of the ...

Where does the gas fueling star formation in brightest cluster galaxies originate [PDF]
, 2016 Aims. We investigate the relationship between X-ray cooling and star formation in brightest cluster galaxies (BCGs). Methods. We present an X-ray spectral analysis of the inner regions, 10 40 kpc, of six nearby cool core clusters (z < 0:35) observed with

Comparing Globular Cluster System Properties with Host Galaxy Environment
The 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.
