Title: Exceptional Swift and Fermi GRBs: Gemini South Rapid Targets of Opportunity

Abstract: Swift and Fermi have sparked a renaissance in the study of GRBs, discovering an unprecedented number of events and promptly alerting the community with accurate localizations. However, it is in the follow-up, particularly at optical/infrared (OIR) wavebands, where the full scientific potential of these missions is realized. This semester our three teams have merged proposals in order to optimize GRB science using the OIR instrument suites on both Gemini telescopes. Our focus is on extreme and rare GRBs that hold the greatest potential as unique probes of the early universe and stellar death: (1) high-redshift bursts (z > 6), offering spectroscopic probes of the universe during reionization; (2) low-redshift bursts (z<1), the keystone events for understanding the nature of the GRB progenitor; (3) Fermi-LAT bursts, which can constrain theories of quantum gravity and place limits on the Lorentz factor of the outflow; and (4) short GRBs, with the goal of constraining their still-mysterious progenitors. Gemini has emerged as the cornerstone facility of global GRB research and we will continue to use our proprietary access on smaller facilities and our wide network of collaborators to maximize the return of Gemini observations.
