GRB 130603 B: Swift detection of a bright short burst • At 15: 49: 14 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130603 B (trigger=557310). Swift slewed immediately to the burst. The BAT onboard calculated location is RA, Dec 172. 209, +17. 045 which is RA(J 2000) = 11 h 28 m 50 s Dec(J 2000) = +17 d 02' 42" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single spike structure with a duration of about 0. 4 sec. The peak count rate was 60000 counts/sec (15 -350 ke. V), at ~0 sec after the trigger.

A search for kilonova emission associated with GRB 130603 B: the smoking gun signature of a compact binary merger event N. R. Tanvir, A. J. Levan, A. S. Fruchter, J. Hjorth, K. Wiersema, R. Tunnicliffe, A. de Ugarte Postigo • • Submitted on 20 Jun 2013 ar. Xiv: 1306. 4971 v 1 The nature of short duration gamma-ray bursts (S-GRBs) represents one of the great unsolved mysteries of astrophysics today. While a favoured model for their origin is the merger of two compact objects (e. g. , neutron stars) this lacks a smoking gun signature to date. However, these mergers are expected to create radioactive species, including heavy r-process elements, which should result in a faint, fast transient in the days following the burst, a so-called kilonova. Recent calculations suggest much energy comes out in the near-infrared in the days following the initial burst. Here we report a search for such an event accompanying GRB 130603 B, the first S-GRB to have a firm redshift established directly from the afterglow. At z=0. 36 the faint transient is expected to peak a few days after the burst at an H-band magnitude of ~25. Observing with the Hubble Space Telescope (HST) nine days post-burst, we indeed find a source at the location of the burst, with these properties, although we cannot yet say whether the light is transient in nature. If it is kilonova emission, then it provides both strong support for the binary neutron star merger theory of short-GRBs and an alternative, un-beamed electromagnetic signature of the most promising gravitational wave sources. We note that we felt compelled to submit this provisional report of our work, despite our HST DDT program being incomplete, due to other authors having already posted an analysis of the publicly available first epoch data.
