Evidence for supernova-synthesized dust from the rising afterglow of GRB071025 at z ~ 5. (2010)

Abstract:We present observations and analysis of the broad-band afterglow of Swift GRB 071025. Using optical and infrared (RIYJHK) photometry, we derive a photometric redshift of 4.4<z<5.2; at this redshift our simultaneous multicolour observations begin at ~30s after the gamma-ray burst trigger in the host frame, during the initial rising phase of the afterglow. ...(more)
Abstract: (hide)
At 04:08:54 UT on 2007 October 25, the Burst Alert Telescope on-board Swift detected GRB 071025 and performed a rapid slew to the GRB location, beginning observations with the X-Ray Telescope at 146s after the trigger. The robotic IR observatory PAIRITEL consists of the 1.3-m Peters Telescope at Mt. Hopkins, Arizona, formerly used for the Two-Micron All-Sky Survey. PAIRITEL responded to the initial Gamma-ray burst Coordinate Network alert at 74.3s and slewed immediately to the source. Observations began at 162s and continued uninterrupted until 3812s, when due to a problem with the observing queue PAIRITEL temporarily slewed to another location. Observations resumed at 9108s and continued for another 2h.
