TL;DR: In this article, the optical drop-out afterglow of Swift GRB 120923A in near-infrared Gemini-North imaging was identified, and a redshift of $z={784}_{-012}^{+006}$ from Very Large Telescope/X-shooter spectroscopy was derived, and the peak 15-150 keV luminosity of the burst was 32 × 1052 erg s−1.

The Relative Rate of LGRB Formation as a Function of Metallicity
J. F. Graham,A. S. Fruchter +1 more
TL;DR: In this paper, the relative rate of LGRB formation as a function of metallicity in the low-redshift universe was investigated and it was shown that LGRBs are preferentially formed in low-metallicity environments.
