[16.20] SCUBA Sub-millimeter Observations of Gamma-Ray Bursters

I. Smith (Rice University), James Clerk Maxwell Telescope GRB Collaboration

We will discuss our ongoing project of sub-millimeter observations of gamma-ray bursters using the SCUBA bolometer array on the James Clerk Maxwell Telescope located on Mauna Kea, Hawaii. Recent observations include GRBs 021004, 021211, and 030115.

Sub-millimeter observations of the early afterglows are of interest because this is where the emission peaks in some bursts in the hours to weeks following the burst. The SCUBA observations determine the breaks in the radio to sub-millimeter to optical spectrum, which can be used to constrain the shock models. Of increasing interest is to look for underlying quiescent sub-millimeter sources that may be dusty star-forming host galaxies.
