On the simultaneous generation of high energy emission and submillimeter/infrared radiation from active galactic nuclei

TL;DR

This paper explores how quasi-linear diffusion in active galactic nuclei can simultaneously generate high-energy gamma-ray emission and submillimeter/infrared radiation, revealing a correlated emission mechanism.

Contribution

It demonstrates that QLD influences electron pitch angles, enabling synchrotron emission at MeV-GeV energies linked with infrared/submillimeter radiation, a novel insight into AGN emission processes.

Findings

QLD affects electron pitch angle distribution.

Synchrotron mechanism can produce MeV-GeV gamma-rays.

Gamma-ray and infrared/submillimeter emissions are correlated.

Abstract

For active galactic nuclei (AGNs) we study the role of the mechanism of quasi-linear diffusion (QLD) in producing the high energy emission in the MeV-GeV domains strongly connected with the submillimeter/infrared radiation. Considering the kinetic equation governing the stationary regime of the QLD we investigate the feedback of the diffusion on electrons. We show that this process leads to the distribution of particles by the pitch angles, implying that the synchrotron mechanism is no longer prevented by energy losses. Examining a reasonable interval of physical parameters, we show that it is possible to produce MeV-GeV gamma-rays, strongly correlated with submillimeter/infrared bands.
