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

Abstract: We propose to make late-time observations of gamma-ray burst (GRB) counterparts, complementary to our companion "Rapid ToO" program. High priority science goals include (a) monitoring of low-redshift (z< 0.5) GRBs to search for photometric or spectroscopic evidence of (or place limits on) emission from accompanying supernovae; (b) observations to help confirm and characterize high-redshift GRB candidates, which, led by our Gemini observations, are providing a unique new window on z>6 star formation and the reionization of the Universe; (c) observations of short-duration bursts, which are likely connected to compact object mergers; and (d) afterglow monitoring for "jet break" burst-collimation measurements, to constrain the total energy output for the highest energy bursts detected by Fermi-LAT. We emphasize that our long-running Gemini campaign, which has allowed us to respond flexibly to rare GRB events, has been very successful and has contributed an essential legacy for Swift: late-time observations have been a key component of this.
