BIMA Observations of Linear Polarization in Sagittarius A* at 112 GHz

Abstract

We report here BIMA array observations of linear polarization in Sagittarius A*, the compact radio source in the Galactic Center. These observations had a resolution of 20 arcsec x 5 arcsec oriented North-South. We do not detect linear or circular polarization at a level of 1.8% (1-sigma) at 112 GHz. This puts a new constraint on models that show a sharp change in linear polarization fraction at 100 GHz.
