Discriminating blazar emission models with high-energy polarimetry: Multi-band predictions and detectability
Sara Capecchiacci, Ioannis Liodakis, Haocheng Zhang +2
Polarimetric properties of blazars provide key constraints on the acceleration mechanisms powering their relativistic jets, the high-energy emission processes involved, and the com…
Detectability of Polarized Gamma-ray Emission from Blazar Flares with COSI
Garrett A. Latiolais, Jorge Otero-Santos, Michela Negro +18
We investigate the detectability of polarized gamma-ray emission from blazar flares with the Compton Spectrometer and Imager (COSI). Using 17 years of Fermi Large Area Telescope ob…
Energy-Dependent Polarization Angle Variability as a Robust Diagnostic for Blazar Flaring Mechanisms
Haocheng Zhang, Benjamin de Jonge, Manel Errando +2
Identifying the physical mechanism driving blazar flares remains a central challenge in high-energy astrophysics. We show that the energy dependence of the standard deviation of th…
Polarization Dynamics of X-Ray Synchrotron Emission from a Multi-Zone Blazar Jet
Benjamin de Jonge, Haocheng Zhang, Manel Errando +2
The polarization of X-ray synchrotron emission in blazars directly probes the magnetic field geometry and particle acceleration processes in relativistic jets. We use particle-in-c…
