Title: Rapid observations of gamma-ray bursts

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 been extremely successful in using Gemini, in coordination with a network of other facilities, to advance this field, and we seek to continue this program. Our primary goals are (i) to locate and study GRBs at very high redshifts (z>5), where they will provide luminous backlights with which to explore the early ISM/IGM, and also the means to identify and characterise their faint host galaxies; (ii) to construct a more complete redshift sample of GRBs; (iii) to detect afterglows and measure redshifts for the class of short-duration bursts, whose nature, despite recent breakthroughs, remains enigmatic; (iv) in conjunction with data from the Fermi satellite, to test the standard jetted, relativistic fireball models. These goals address central questions of contemporary astrophysics and cosmology.
