Turning to the Dark Side: Evidence for Circumburst Extinction of Gamma-Ray Bursts with Dark Optical Afterglows
Daniel E. Reichart, Sarah A. Yost
We present evidence that the majority of rapidly-, well-localized gamma-ray bursts with undetected, or dark, optical afterglows, or `dark bursts' for short, are most likely the res…

Broadband Observations of the Afterglow of GRB 000926: Observing the Effect of Inverse Compton Scattering and Evidence for a High-Density Environment
F. A. Harrison, S. A. Yost, R. Sari +21
GRB 000926 has one of the best-studied afterglows to-date, with multiple X-ray observations, as well as extensive multi-frequency optical and radio coverage. Broadband afterglow ob…
