  In this work, I present a qualitative discussion on the prospect of
production of ultra-high photons in blazars. The sources are a subclass of
active galactic nuclei which host supermassive black holes and fire
relativistic jets into the intergalactic medium. The kpc scale jets are
believed to be dominated by Poynting flux and constitute one of the most
efficient cosmic particle accelerators, that potentially are capable of
accelerating the particles up to EeV energies. Recent IceCube detection of
astrophysical neutrino emission in coincidence with the enhanced gamma-ray from
Tev blazar TXS 0506 + 056 further supports hadronic models of blazar emissions
in which particle acceleration processes such as relativistic shocks, magnetic
re-connection, and relativistic turbulence could energize hardrons, e. g.
protons, up to energies equivalent to billions of Lorentz factors. The ensuing
photo-pionic processes may then result in gamma-rays accompanied by neutrino
flux. Furthermore, the fact that blazars are the dominant source of observed
TeV emission encourages us to search for signatures of acceleration scenarios
that would lead to the creation of ultra-high energy photons.
