We investigate the polarization of Compton scattered X-rays from relativistic
jets in active galactic nuclei using Monte Carlo simulations. We consider three
scenarios: scattering of photons from an accretion disk, scattering of cosmic
microwave background (CMB) photons, and synchrotron self-Comptonization (SSC)
within the jet. For Comptonization of thermal disk photons or CMB photons the
maximum linear polarization attained is slightly over 20% at viewing angles
close to 90 degrees. The value decreases with the viewing inclination. For SSC,
the maximum value may exceed 80%. The angle dependence is complicated, and it
varies with the photon i…(mehr)

polarization, in addition to multi-wavelength spectra, can distinguish certain
models for emission and particle acceleration in relativistic jets.
