Host galaxy R magnitudes plotted versus redshift for short GRBs
Host galaxy R magnitudes plotted versus redshift for short GRBs (solid black circles, arrows), long GRBs (gray squares), and galaxies in the HST/ACS Early Release Observation fields VV 29 and NGC 4676. In all samples a trend of increasing apparent magnitude with redshift is seen. The clear magnitude–redshift relation for short GRBs suggests that the faint host galaxies discussed in this paper are located at z ~ 1.
