Abstract
Long-duration gamma-ray bursts (GRBs) allow us to pinpoint and study star-forming galaxies in the early universe, thanks to their orders of magnitude brighter peak luminosities compared to other astrophysical sources, and their association with the deaths of massive stars. We present Hubble Space Telescope Wide Field Camera 3 detections of three Swift GRB host galaxies lying at redshifts z = 5.913 (GRB 130606A), z = 6.295 (GRB 050904), and z = 6.327 (GRB 140515A) in the F140W (wide-JH band, λobs ∼ 1.4μm) filter. The hosts have magnitudes (corrected for Galactic extinction) of mλobsAB = 26.34-0.16+0.14, 27.56-0.22+0.18, and 28.30-0.33+0.25, respectively. In all three cases, the probability of..
