Beschreibungen/Notizen

• We present the optical discovery and sub-arc-second optical and X-ray localization of the afterglow of the short GRB 120804A, as well as optical, near-IR, and radio detections of its host galaxy. X-ray observations with Swift/XRT, Chandra, and XMM-Newton extending to delta t [approximate] 19 days reveal a single power-law decline. The expected fraction of luminous infrared galaxies in the short GRB host sample is ~0.01 and ~0.25 (for pure stellar mass and star formation weighting, respectively). Thus, the observed fraction of two events in about 25 hosts (GRBs 120804A and 100206A) appears to support our previous conclusion that short GRBs track both stellar mass and star formation activity.
