The Origin of UCDs in the Virgo Cluster
E. A. Evstigneeva, M. D. Gregg, M. J. Drinkwater
We present the internal velocity dispersions and spectral line indices for six Virgo ultra-compact dwarf (UCD) galaxies obtained from spectroscopy with the Keck II 10-m telescope.…
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…
Uncovering High-z Clusters Using Wide-Angle Tailed Radio Sources
E. L. Blanton, M. D. Gregg, D. J. Helfand +2
The morphologies of wide-angle tailed (WAT) radio sources (edge-darkened, C-shaped, FR I radio sources) are the result of confinement and distortion of the radio lobes by the dense…
Cluster--Galaxy Interactions in Coma
Michael D. Gregg, Bradford P. Holden, Michael J. West
The galaxies NGC 4911 and 4921 in the Coma cluster provide spectacular examples of luminous, grand design spirals passing through the hot intracluster medium of a rich cluster of g…
