The Linear Polarization of Sagittarius A* II. VLA and BIMA Polarimetry at 22, 43 and 86 GHz
نویسنده
چکیده
We present a search for linear polarization at 22 GHz, 43 GHz and 86 GHz from the nearest super massive black hole candidate, Sagittarius A*. We find upper limits to the linear polarization of 0.2%, 0.4% and 1%, respectively. These results strongly support the conclusion of our centimeter wavelength spectro-polarimetry that Sgr A* is not depolarized by the interstellar medium but is in fact intrinsically depolarized. Subject headings: Galaxy: center — galaxies: active — scattering — polarization

متن کاملThe Linear Polarization of Sagittarius A* I. VLA Spectro-polarimetry at 4.8 and 8.4 GHz
Synchrotron radiation from active galactic nuclei (AGN) is often highly polarized. We present a search for linear polarization with the Very Large Array (VLA) at 4.8 GHz and 8.4 GHz from the nearest AGN, Sagittarius A*. As a part of this study we used spectro-polarimetric data that were sensitive to a rotation measure (RM) as large as 3.5 × 10 rad m at 4.8 GHz and 1.5 × 10 rad m at 8.4 GHz. The...
متن کاملBIMA Observations of Linear Polarization in Sagittarius A* at 112 GHz
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 × 5 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.

As a part of this study we used spectro-polarimetric data that were sensitive to a rotation measure (RM) as large as 3:5 10 6 rad m ?2 at 4.8 GHz and 1:5 10 7 rad m ?2 at 8.4 GH...

We describe recent results for Sgr A*, M81* and other low luminosity active galactic nuclei. We have conducted linear and circular polarimetry over a frequency range of 1.4 to 230 GHz and detected a variety of phenomena. The polarization properties of the studied sources are substantially different from higher powered AGN. In the case of Sgr A*, we are able to eliminate ADAFs and Bondi-Hoyle fl...
