要旨
We investigate the innermost structure of black hole-disk-jet systems through polarization images. First, we focus on linear and circular polarization (LP and CP) separation along the jet, based on our general relativistic radiation transfer code. We find that the LP and CP components are separated by the Faraday effects. Next, we discuss the flipping of the polarization by nonthermal electrons. We show that the LP vectors flip in the counter-side jet and the photon ring. Finally, we study the connection between the horizon-scale dynamics and the extended jet images. We find that the jet widths are indicative of the magnetic flux on the horizon.
