Exploiting High-Energy Polarization in Blazars
July 29, 2019
The spectral energy distributions (SEDs) and variability of astrophysical sources can be modeled in many different ways, in particular, the production of $X$-rays and $\gamma$-rays in the SEDs of blazars. High-energy polarimetry can probe the most active jet regions with the most efficient particle accelerations, and thus serve as a powerful tool to distinguish between models. We summarize the scientific potential and model predictions for high-energy polarization of blazar jets. The advantages of using Monte Carlo methods to study high-energy polarization from anisotropic Compton scattering, by thermal and non-thermal particles, will be discussed. This will reinforce the use of measurements of polarization signatures to suggest observational strategies in future projects and to use polarization as a diagnostic to distinguish between leptonic and hadronic high-energy emission from blazars.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
