The Circular Polarization of Sagittarius A at Submillimeter Wavelengths

We report the first detections of circularly polarized emission at submillimeter wavelengths from the compact radio source and supermassive black hole candidate Sgr A* at a level of 1.2% + or - 0.3% at 1.3 mm wavelength (230 GHz) and 1.6% + or - 0.3% at 860 mu m (345 GHz) with the same handedness, l...
