Аннотация:We present late-time Hubble Space Telescope imaging of the fields of six Swift GRBs lying at 5.090% confidence. Although it is not yet possible to make stronger statements, in the future, with larger samples and a fuller understanding of the conditions required for GRB production, studies like this hold great potential for probing the nature of star formation, the shape of the galaxy luminosity function, and the supply of ionizing photons in the early universe.
