Title: Late-time Observations of Exceptional Swift and Fermi GRBs: Gemini South Standard Targets of Opportunity

Abstract: We propose to make late-time observations of gamma-ray burst (GRB) afterglows initially observed under our companion "Rapid TOO" Gemini program. Science goals for "Standard TOO" observations include: (1) low-redshift GRBs, to exploring the diversity of GRB-SNe; (2) high-redshift GRBs, which are providing a unique perspective on z>5 star formation and reionization; (3) short-duration bursts, which are likely connected to compact object mergers; and (4) Fermi-LAT bursts, which include the most luminous and relativistic GRBs. Late-time observations are required to fully characterize these bursts, for example, by constraining burst explosion geometry and total energy through the detection of jet breaks. Even as a mature mission, Swift continues to supply unexpected discoveries, as does the younger Fermi mission. Gemini forms the cornerstone of our follow-up effort; its capabilities are essential for capitalizing on the remaining years of the Swift mission. Our merged global collaboration aims to secure Swift's legacy by focusing on the extreme and rare GRBs that hold the greatest potential as unique probes of the early universe and stellar death. We emphasise that our long-running campaign at Gemini has been very successful, allowing us to respond flexibly to rare GRB events: late-time observations have been a critical component of this.
