POLAMI Multi-Wavelength Polarization Study of AGN Jets: A Millimeter-Optical Comparison

C. Casadio, D. Blinov, I. Agudo +20

Millimeter-band polarimetry offers a powerful probe of AGN jets, accessing regions less affected by opacity and Faraday rotation than at longer radio wavelengths. As part of the PO…
