GRBs 070429B and 070714B: The High End of the Short-Duration Gamma-Ray Burst Redshift Distribution
S. Bradley Cenko, Edo Berger, Ehud Nakar +11
We present optical spectra of the host galaxies of the short-duration gamma-ray burst GRB 070429B and the likely short-duration with extended emission GRB 070714B. In both cases, w…
High-Resolution Spectroscopy of GRB030226: Features of a Massive Star Progenitor or Intervening Absorption Systems?
Min-Su Shin, Edo Berger, Bryan E. Penprase +7
We present a high-resolution Keck/ESI spectrum of GRB, which exhibits four absorption systems at z=1.04329, 1.95260, 1.96337, and 1.98691. The two highest redshift systems, separat…
Fine-Structure FeII and SiII Absorption in the Spectrum of GRB 051111: Implications for the Burst Environment
E. Berger, B. E. Penprase, D. B. Fox +4
We present an analysis of fine-structure transitions of FeII and SiII detected in a high-resolution optical spectrum of the afterglow of GRB 051111 (z=1.54948). The fine-structure…
The afterglow of GRB050709 and the nature of the short-hard gamma-ray bursts
D. B. Fox, D. A. Frail, P. A. Price +33
The final chapter in the long-standing mystery of the gamma-ray bursts (GRBs) centres on the origin of the short-hard class, suspected on theoretical grounds to result from the coa…
A Morphological Study of Gamma-Ray Burst Host Galaxies
C. Wainwright, E. Berger, B. E. Penprase
We present a comprehensive study of the morphological properties of 42 gamma-ray burst (GRB) host galaxies imaged with the Hubble Space Telescope in the optical band. The purpose o…
