Abstract (from CDS):

We report here Berkeley-Illinois-Maryland Association array observations of linear polarization in Sagittarius A*, the compact radio source in the Galactic center. These observations had a resolution of 20"x5" oriented north-south. We do not detect linear or circular polarization at a level of 1.8% (1 σ) at 112 GHz. This puts a new constraint on models that show a sharp change in linear polarization fraction at 100 GHz.
