[101.03] VLA Searches for the Radio Counterparts of Gamma-ray Bursters

D. A. Frail (NRAO), S. R. Kulkarni (Caltech), C. O. Heinke (Carleton College), C. Carpenter (Harvard), Beppo-SAX GRB Team

We report on the results of a radio monitoring campaign of the arcminute-sized error boxes toward several gamma-ray bursts. The fields of 11 well-localized gamma-ray bursts were observed with the Very Large Array (VLA), mostly at 20-cm, over a period of several years. Examples include the May 1, 1992 burst, localized with the Third Interplanetary Network, and the recent Beppo-SAX burst GRB 960720. These observations sample a range of postburst timescales and allow us to constrain the parameter space in which predictions of a long-lived, time-variable radio counterpart can be applied.
