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…
Disentangling microlensing and differential extinction in the double QSO HE0512-3329
O. Wucknitz, L. Wisotzki, S. Lopez +1
We present the first separate spectra of both components of the small-separation double QSO HE0512-3329 obtained with HST/STIS in the optical and near UV. The similarities especial…
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…
