Title: Quick Response to GRBs: probing underlying supernovae and rapid variability

Abstract: We propose to continue our program of Quick Response observations of gamma-ray burst afterglows using the Gemini South Acquisition Camera. The unusual combination of excellent sensitivity and rapid readout enables unique science goals. First, intermediate and late-time monitoring of GRB afterglows, as they become too faint for 4m class followup, provides a bridge to late-time HST/ACS photometry and STIS spectroscopy. This will allow us to address one of the central questions in GRB research: are high redshift GRBs associated with supernovae? Spectroscopic confirmation of an underlying supernova would settle this issue. Second, high time-resolution observations of GRB afterglows at early times offer a new window into the physics of these extreme events, and a possible route to finding optical afterglows for bursts previously regarded as "dark". The increasing speed of response of HETE-II, INTEGRAL, and (from Dec 03) SWIFT, supplemented by an expanding array of roboti!
