Abstract
PG 1407+265 is a radio quiet quasar but has a relativistic jet. In this report, we show some peculiar properties of its optical and X-ray emissions, which indicate their possible non-thermal origins produced from jet. We use a simple synchrotron + synchrotron self Compton (SSC) model to fit the emissions with different ratios of energy densities between magnetic field and electrons (η=UB/Ue), which predict different γ-ray luminosity. The First LAT AGN Catalog (1LAC) did not include PG 1407+265, which indicates an upper limit of γ-ray luminosity. This upper limit constrains the ratio unreasonable large (η>10^4-10^5). This inversely indicates that the optical and X-ray emissions may be not produced from the beaming jet. We discuss the physical implications of these results.
