Particle Acceleration in Multimessenger & MeV Blazars

The acceleration mechanisms in blazars jets are currently uncertain. In order to study particle acceleration in this environment, we have to filter through the additional uncertainty in the high-energy emission processes. What has become clear regardless is that to understand either requires simulating both acceleration and cooling processes accurately in the particle population. The advent of new data types, like high-energy polarization and coincident neutrinos point toward shock acceleration and leptohadronic composition for at least some blazars. Thus, I present some theoretical models that treat these cases for a sample of MeV bright and Multimessenger blazars relevant for the AMEGO-X mission concept and future MeV missions.
