Zooming in on the locations of short gamma-ray bursts

This program will observe the locations of 22 short gamma-ray bursts with the WFC3/IR camera in the F160W filter in order to obtain high resolution, sensitive, infrared observations of their host galaxies. These observations will double the sample of sGRB host galaxies observed with HST and reveal accurately their locations with respect to the half-light radii of their host galaxies. In addition, we target 9 events that are observationally hostless even in deep ground based observations. These 9 targets will recieve 2 orbits in F160W to search for faint underyling host galaxies. The program will use 31 orbits - 1 orbit x 13 targets which already have known host galaxies and 2 obits x 9 targets which lack a host galaxy.
