BIMA Observations of the Soft Gamma-Ray Repeaters

Smith, I. A., Chernin, L. M., & Hurley, K.

The far infrared observations of the quiescent counterparts to the Soft Gamma-Ray Repeaters SGR1806-20 and SGR1900+14 indicate that these sources contain both point source and extended components. We observed them at 85 GHz using the Berkeley-Illinois-Maryland Array, and found that neither of them had detectable point source emission. These results are consistent with other millimeter and submillimeter upper limits, suggesting that the bright far infrared point source emission is from dust. The point source upper limit for SGR1806-20 is not inconsistent with the observation of a point-like "core" to the radio nebula.
