The Astrophysics of the Most Energetic Gamma-Ray Bursts The Large Area Telescope (LAT) of Fermi has found a sample of highly relativistic gamma-ray bursts (GRBs), which may be among the most energetic bursts ever discovered. Here we propose to use Chandra and HST to follow the late time X-ray and optical light curves of a LAT detected burst that also has excellent early multiwavelength coverage. Our observations, in conjunction with the Fermi data, will allow us to measure the energy and the bulk Lorentz factor of the explosion. Recent work on some of the most powerful GRBs begins to substantially constrain physical models of the progenitors. The energetics of the highly relativistic LAT bursts may greatly strengthen these constraints and provide new insight into the currently unknown mechanism that determines the energy of a GRB. We plan five visits with HST: the first an orbit long, the second and third each two orbits long, with the fourth and fith three orbits long. The first visit will occur about around twenty days after outburst. The second will be around forty days after outburst. The third 80 days and the fourth 160. The exact times will be scaled according to the decay seen from the ground. The fith visit will be taken at least nine months after the burst to allow an accurate host subtraction. We will use the UVIS camera on WFC3 because WFC3 easily has as good sensitivity on point sources as ACS with smaller detector-induced noise sources (CTE, bias-striping, etc). We will choose the filter at the time of the ToO to match the best observed band from the ground (most likely a red band) and to avoid a SN contribution if possible.
