Interferometric Detection of Linear Polarization from Sagittarius A* at 230 GHz

Interferometric Detection of Linear Polarization from Sagittarius A* at 230 GHz

We measured the linear polarization of Sagittarius A* to be 7.2% ± 0.6% at 230 GHz using the BIMA array with a resolution of 36 × 09. This confirms the previously reported detection with the James Clerk Maxwell Telescope (JCMT) 14 m antenna. Our high-resolution observations demonstrate that the polarization …
