The ACS Fornax Cluster Survey. X. Color Gradients of Globular Cluster Systems in Early-Type Galaxies
Chengze Liu, Eric W. Peng, Andres Jordan +4
We use the largest homogeneous sample of globular clusters (GCs), drawn from the ACSVCS and ACSFCS, to investigate the color gradients of GC systems in 76 early-type galaxies. We f…
The ACS Fornax Cluster Survey. IV. Deprojection of the Surface Brightness Profiles of Early-Type Galaxies in the Virgo and Fornax Clusters: Investigating the "Core/Power-Law Dichotomy"
Lisa Glass, Laura Ferrarese, Patrick Cote +8
Although early observations with the Hubble Space Telescope (HST) pointed to a sharp dichotomy among early-type galaxies in terms of the logarithmic slope gamma' of their central s…
UCDs in the Coma Cluster
Kristin Chiboucas, R. Brent Tully, Ronald O. Marzke +6
As part of the HST/ACS Coma Cluster Treasury Survey, we have undertaken a Keck/LRIS spectroscopic campaign to determine membership for faint dwarf galaxies. In the process, we disc…
Surface Brightness Fluctuations in the Hubble Space Telescope ACS/WFC F814W Bandpass and an Update on Galaxy Distances
John P. Blakeslee, Michele Cantiello, Simona Mei +7
We measure surface brightness fluctuation (SBF) magnitudes in the F814W filter and g-I colors for nine bright early-type Fornax cluster galaxies imaged with the Hubble Space Telesc…
The HST/ACS Coma Cluster Survey. II. Data Description and Source Catalogs
Derek Hammer, Gijs Verdoes Kleijn, Carlos Hoyos +45
The Coma cluster was the target of a HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was interrupted by the ACS instrument…
The ACS Fornax Cluster Survey. VIII. The Luminosity Function of Globular Clusters in Virgo and Fornax Early-Type Galaxies and its Use as a Distance Indicator
Daniela Villegas, Andres Jordan, Eric W. Peng +8
We use a highly homogeneous set of data from 132 early-type galaxies in the Virgo and Fornax clusters in order to study the properties of the globular cluster luminosity function (…
