Linear and Circular Polarization Properties of Jets [PDF]
, 2003 I discuss the transfer of polarized synchrotron radiation in relativistic jets. I argue that the main mechanism responsible for the circular polarization properties of compact synchrotron sources is likely to be Faraday conversion and that, contrary to ...

The Polarized Emission of AGN at Millimeter Wavelengths as Seen by POLAMI
Galaxies, 2022 We review results from the POLAMI program, which monitors the polarization properties of 36 blazars at the IRAM 30 m telescope. We found that the variability of the degree of linear polarization is faster and of higher amplitude at 1 mm than at 3 mm and ...
