High energy photon emission from wakefields and its signatures in astrophysical Blazars

Episodic eruptions of accretion disks of AGNs (and Blazars) due to the Magneto-Rotational-Instability are related to the excitation of intense Alfv$'e$n waves and their subsequently mode converted EM pulses. These intense pulses are related to the emission of bursts of $$gamma$$ rays and extreme high energy cosmic ray (EHECR) genesis in AGN and Blazars. Wakefield acceleration and pondermotive acceleration of electrons give rise to $$gamma$$ ray emissions of the above through synchrotron radiation which can undergo inverse-Compton scattering to attain high X-ray energies. We study additional emissions of $$gamma$$ rays by the betatron oscillations and QED radiative processes in the intense accelerating fields.
