Unveiling Star-forming Galaxies through GRB Afterglow Absorption-line Observations

Hsiao-Wen Chen (UChicago)

Long-duration gamma-ray bursts originate in the catastrophic death of massive stars. Optical afterglows immediately following these bursting events are therefore signposts of distant star-forming galaxies that are otherwise difficult to uncover. I will discuss constraints on the host interstellar medium obtained from rapid spectroscopic follow-up of optical afterglows.
