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.
