Globular Cluster Populations in Four Early-Type Poststarburst Galaxies
Aparna Maybhate, Paul Goudfrooij, Francois Schweizer +2
We present a study of the globular cluster systems of four early-type poststarburst galaxies using deep g and I-band images from the ACS camera aboard the Hubble Space Telescope (H…
Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
A large population of recently-quenched red-sequence dwarf galaxies in the outskirts of the Coma Cluster
Russell J. Smith, Ronald O. Marzke, Ann E. Hornschemeier +6
We analyse the stellar populations of 75 red-sequence dwarf galaxies in the Coma cluster, based on high signal-to-noise spectroscopy from the 6.5m MMT. The sample covers a luminosi…
The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design
David Carter, Paul Goudfrooij, Bahram Mobasher +34
We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey…
Evidence for Three Subpopulations of Globular Clusters in the Early-Type Post-Starburst Shell Galaxy AM 0139-655
A. Maybhate, P. Goudfrooij, F. Schweizer +2
We present deep HST ACS images of the post-starburt shell galaxy AM 0139-655. We find evidence for the presence of three distinct globular cluster subpopulations associated with th…
Early Optical Polarization of a Gamma Ray Burst Afterglow
Carole G. Mundell, Iain A. Steele, Robert J. Smith +10
We report the optical polarization of a gamma ray burst (GRB) afterglow, obtained 203 seconds after the initial burst of gamma rays from GRB 060418, using a ring polarimeter on the…
