TITLE: GCN CIRCULAR NUMBER: 14365 SUBJECT: GRB 130408A - VLT/X-shooter redshift determination DATE: 13/04/09 01:47:22 GMT FROM: Jens Hjorth at U.Copenhagen J. Hjorth (DARK), A. Melandri (INAF-OAB), D. Malesani (DARK), T. Kruehler (DARK), and D. Xu (DARK) report on behalf of a larger collaboration: We observed the afterglow of GRB 130408A (Lien et al. GCN 14361; Melandri et al. GCN 14362; Siegel et al. GCN 14363) with the X-shooter spectrograph on the ESO VLT, beginning approximately 1 h 55 min after the BAT trigger. We detect damped Ly-alpha absorption, Ly-alpha forest, the Lyman break, and numerous metal lines consistent with a redshift of 3.758. We thank Maria Teresa Ruiz, Avril Day-Jones, Cedric Ledoux, Leo Rivas, Alex Correa, and Lorenzo Monaco for conducting the observations.
