The BIMA Search for Millimeter-Wavelength Counterparts to Gamma-Ray Bursters

Gruendl, R. A., Smith, I. A., Forester, R., Lo, K. Y., Liang, E., and Leventhal, M.

We present the latest results from our on-going campaign to detect gamma-ray burst counterparts at millimeter-wavelengths using the Berkeley-Illinois-Maryland Association array (BIMA). BIMA is well suited for performing counterpart searches, since it can map the several arc-minute error boxes from initial burst locations, as well as performing deep stares on any better localized counterparts. Here we summarize our observations of GRBs 970111, 970228, 970508, 970815, and 970828 with emphasis on the last three to show the constraints that BIMA can place on the brightness of millimeter-wavelength emission from these bursts.
