ABSTRACT – Estimates of proton energies in extragalactic…
It is shown that inelastic proton collisions in extragalactic radio sources can account for their radio and -ray emissions. The proton Lorentz-factor p responsible for -ray emission is estimated to lie between 1.4 and 86. But for the radio emission (with e ~ 103-104) the estimated p values lie between 7 to 300. The estimates of total particle and magnetic energy for a typical radio source is in agreement with equipartition theory.
