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

Abstract: Swift and Fermi have led a renaissance in the study of GRBs, discovering an unprecedented number of events and promptly alerting the community to 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. We have recently merged two GRB ToO teams in order to optimize our 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 universe and stellar death: 1) high-redshift events (z > 6), offering spectroscopic probes of the universe during reionization, 2) low-redshift events (z < 1), allowing searches for and detailed studies of accompanying supernovae, 3) Fermi-LAT bursts, which require redshift measurements in order to 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 work in our wide network of collaborators to maximize the return of Gemini observations.
