Abstract:
We present broad-band multiwavelength observations of GRB 080310 at
redshift z=2.43. This burst was bright and long-lived, and unusual in
having extensive optical and near-infrared (IR) follow-up during the
prompt phase. Using these data we attempt to simultaneously model the
gamma-ray, X-ray, optical and IR emission using a series of prompt
pulses and an afterglow component.
Description:
On 2008 March 10 the Swift Burst Alert Telescope (BAT) triggered and
located GRB 080310 (trigger number 305288) on board at 08:37:58 UT
(Cummings et al., 2008GCN..7382....1C 2008GCN..7382....1C). Swift slewed immediately which
enabled the narrow field instruments to begin observing the burst 89s
after the trigger. The burst was detected by the XRT and UVOT (white
filter), with the latter providing the best Swift position of
RA=14:40:13.80 and DE=-00:10:29.8 (J2000) with a 1σ error radius
of 0.6 arcsec.
In addition to Swift observations, and those instruments already
mentioned, GRB 080310 was also observed on the ground with numerous
optical and near-infrared (NIR) facilities, including Rapid Eye Mount
(REM), Very Large Telescope (VLT) and the Faulkes Telescope North
(FTN).
