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'' x
5'' oriented North-South. We do not detect linear or
circular polarization at a level of 1.8% at 112 GHz. This puts a new
constraint on models that show a sharp change in linear polarization
fraction at 100 GHz.
