High-energy polarimetry emission models

Listed in IVOA Registry (Virtual Observatory)

Polarimetric properties of blazars provide key constraints on the acceleration mechanisms powering their relativistic jets, the high-energy emission processes involved, and the composition of the jet itself.

Description

We present a multi-band polarimetric study spanning from soft X-rays to gamma-ray energies, considering several bands for current and future missions (0.275keV, 2-8keV, 0.5-10keV, 6-35keV, 0.2-5MeV, and 1-100GeV). Our sample is drawn from the RoboPol Monitoring Program, a statistically complete gamma-ray selected sample including low-, intermediate-, and high-synchrotron-peaked blazars.

Using spectral energy distribution fitting performed with the Bjet_MCMC tool, we give predictions on the flux expected for each source in the selected energy bands. We model the polarimetric signatures under three competing emission scenarios: leptonic, hadronic, and hybrid. The detectability of each source is assessed by accounting for the instruments' minimum detectable polarisation (MDP) and by computing the probability of the detection in a blind survey.

We show that simultaneous multi-wavelength observations can effectively discriminate between competing emission models due to the difference in the expected polarisation degree (PD). Finally, we derive sensitivity requirements for future gamma-ray polarimetric missions aimed at increasing the number of detectable sources.
