High-Redshift Starbursting Dwarf Galaxies Revealed by GRB Afterglows
Hsiao-Wen Chen, Daniel A. Perley, Lindsey K. Pollack +7
We present a study of 15 long-duration gamma-ray burst (GRB) host galaxies at z>2. The GRBs are selected with available early-time afterglow spectra in order to compare interstella…
A Survey for NV Absorption at z~z_GRB in GRB Afterglow Spectra: Clues to Gas Near the Progenitor Star
Jason X. Prochaska, Miroslava Dessauges-Zavadsky, Enrico Ramirez-Ruiz +1
We survey NV absorption in the afterglow spectra of long-duration gamma-ray bursts (GRBs) with the intent to study highly ionized gas in the galaxies hosting these events. We ident…
GRB 071003: Broadband Follow-up Observations of a Very Bright Gamma-Ray Burst in a Galactic Halo
D. A. Perley, W. Li, R. Chornock +26
The optical afterglow of long-duration GRB 071003 is among the brightest yet to be detected from any GRB, with R ~ 12 mag in KAIT observations starting 42 s after the GRB trigger,…
From Shock Breakout to Peak and Beyond: Extensive Panchromatic Observations of the Type Ib Supernova 2008D associated with Swift X-ray Transient 080109
Maryam Modjaz, W. Li, N. Butler +38
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis…
A STIS Survey for OVI Absorption Systems at 0.12 < z < 0.5 I.: The Statistical Properties of Ionized Gas
Christopher Thom, Hsiao-Wen Chen
We have conducted a systematic survey for intervening OVI absorbers in available echelle spectra of 16 QSOs at z_QSO = 0.17-0.57. These spectra were obtained using HST/STIS with th…
The Baryon Content of Dark Matter Halos: Empirical Constraints from MgII Absorbers
Hsiao-Wen Chen, Jeremy L. Tinker
We have initiated a survey of MgII 2796, 2803 absorbers near known galaxies at projected distances rho<~100 h^-1 kpc to a background QSO, in order to constrain the extent and cover…
