High Metallicity LGRB Hosts
J. F. Graham, A. S. Fruchter, E. M. Levesque +9
We present our imaging and spectroscopic observations of the host galaxies of two dark long bursts with anomalously high metallicities, LGRB 051022 and LGRB 020819B, which in conju…
Spin-Down of the Long-Period Accreting Pulsar 4U 2206+54
Mark H. Finger, Nazar R. Ikhsanov, Colleen A. Wilson-Hodge +1
4U 2206+54 is a high mass X-ray binary which has been suspected to contain a neutron star accreting from the wind of its companion BD +53 2790. Reig et al. have recently detected 5…
GRB051022: physical parameters and extinction of a prototype dark burst
Evert Rol, Alexander van der Horst, Klaas Wiersema +19
GRB051022 was undetected to deep limits in early optical observations, but precise astrometry from radio and X-ray showed that it most likely originated in a galaxy at z~0.8. We re…
Prompt and Afterglow Emission Properties of Gamma-Ray Bursts with Spectroscopically Identified Supernovae
Y. Kaneko, E. Ramirez-Ruiz, J. Granot +8
We present a detailed spectral analysis of the prompt and afterglow emission of four nearby long-soft gamma-ray bursts (GRBs 980425, 030329, 031203, and 060218) that were spectrosc…
Jet Breaks in Short Gamma-Ray Bursts. II: The Collimated Afterglow of GRB 051221A
David N. Burrows, Dirk Grupe, Milvia Capalbi +8
We report the best evidence to date of a jet break in a short Gamma-Ray Burst (GRB) afterglow, using Chandra and Swift XRT observations of the X-ray afterglow of GRB 051221A. The c…
Jet Breaks in Short Gamma-Ray Bursts. I: The Uncollimated Afterglow of GRB 050724
D. Grupe, D. N. Burrows, S. K. Patel +5
We report the results of the \chandra observations of the \swift-discovered short Gamma-Ray Burst GRB 050724. \chandra observed this burst twice, about two days after the burst and…
