Megan E. Eckart, Elise S. Laird, Daniel Stern +3
The Serendipitous Extragalactic X-ray Source Identification (SEXSI) Program is designed to expand significantly the sample of identified extragalactic hard X-ray sources at interme…
A Search for Discrete X-ray Spectral Features in a Sample of Bright Gamma-ray Burst Afterglows
Masao Sako, Fiona Harrison, Robert Rutledge
(abridged) We present uniform, detailed spectral analyses of gamma-ray burst (GRB) X-ray afterglows observed with ASCA, Beppo-SAX, Chandra, and XMM-Newton, and critically evaluate…
