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…
