AGNs with hard gamma-ray emission identified so far are radio-loud. III Zw 2 is a radio intermediate AGN with a relativistic jet. We study its spectral energy distribution (SED) and find that the broad band emissions are dominated by the non-thermal emissions from the jet. We model its SED through a synchrotron + inverse Compton (IC) model. The results show that the IC component of III Zw 2 peaks at a few MeV, and the flux density drops rapidly at higher energy with photon index Gamma… Expand

THE CENTRAL ENGINES OF TWO UNUSUAL RADIO-INTERMEDIATE/QUIET ACTIVE GALACTIC NUCLEI: III Zw 2 AND PG 1407+265
We use the accretion disk/corona + jet model to fit the multi-band spectral energy distributions (SEDs) of two unusual radio-intermediate/quiet quasars. It is found that the optical/UV emission ofExpand
A puzzle of the radio-quiet quasar PG 1407+265: Are optical and X-ray emissions produced from a relativistic jet?
PG 1407+265 is a radio quiet quasar that has a relativistic jet. In this report, we show some peculiar properties of its optical and X-ray emissions, which indicate possible non-thermal originsExpand
