The ACS Virgo Cluster Survey V: SBF Calibration for Giant and Dwarf Early-type Galaxies
Simona Mei, John P. Blakeslee, John L. Tonry +7
As part of the Advanced Camera for Survey (ACS) Virgo Cluster Survey, we have measured Surface Brightness Fluctuations (SBF) in a sample of 100 early-type Virgo galaxies. Distances…
XMM Cluster Survey: X-ray source identification using the Sloan Digital Sky Survey
Kate R. Land, Robert C. Nichol, Michael Davidson +8
[ABRIDGED] The XMM Cluster Survey (XCS) is predicted to detect thousands of clusters observed serendipitously in XMM-Newton pointings. We investigate automating optical follow-up o…
The Ghosts of Galaxies: Tidal Debris in Clusters
Michael D. Gregg, Michael J. West
Gravitational interactions in rich clusters can strip material from the outer parts of galaxies or even completely disrupt entire systems, giving rise to large scale, low surface b…
Galaxy Disruption Caught in the Act
A. M. Karick, M. J. Drinkwater, M. West +2
Direct evidence of stellar material from galaxy disruption in the intra-cluster medium (ICM) relies on challenging observations of individual stars, planetary nebulae and diffuse o…
Intergalactic Globular Clusters
Michael J. West, Patrick Cote, Henry C. Ferguson +5
We confirm and extend our previous detection of a population of intergalactic globular clusters in Abell 1185, and report the first discovery of an intergalactic globular cluster i…
Galaxy Deconstruction: Clues from Globular Clusters
Michael J. West
The present-day globular cluster populations of galaxies reflect the cumulative effects of billions of years of galaxy evolution via such processes as mergers, tidal stripping, acc…
