Title: Rapid observations of gamma-ray bursts with Gemini-S

Abstract: Rapid observations of gamma-ray bursts are critical to probing their exotic physics and using GRBs themselves as probes of the universe. Our collaboration has recently found the most distant known object, GRB 090423 at z=8.2, and continues to use Gemini (supported by other facilities) to study distant and extreme bursts, and explore the diversity of their hosts and progenitors. Our approach to both study individual key events, and build up statistical samples. The primary goals are (i) to detect afterglows and hosts, and measure redshifts for the class of short-duration bursts, whose nature, despite recent breakthroughs, remains enigmatic; (ii) to locate and study GRBs at very high redshifts (z>5) where they provide a window on early galaxy evolution and the IGM; (iii) to construct a more complete redshift sample of GRBs and constrain the redshift evolution of the mass-metallicity relation; (iv) in conjunction with X-ray (Swift/Chandra/XMM) and high-energy gamma ray (Fermi) data, to test the standard jetted, relativistic fireball models and to explore the connection between long-duration gamma-ray bursts and the core-collapse events that accompany them.
