Why Haven’t Many of the Brightest Radio Loud Blazars Been Detected in Gamma-rays by Fermi ?
We use the complete MOJAVE 1.5 Jy sample of active galactic nuclei (AGN) to examine the gammaray detection statistics of the brightest radio-loud blazars in the northern sky. We find that 23% of these AGN were not detected above 0.1 GeV by the Fermi LAT during the 4-year 3FGL catalog period partly because of an instrumental selection effect, and partly due to their lower Doppler boosting factor...

15 صفحه اولExtragalactic Gamma–rays: Gamma Ray Bursts and Blazars
The extragalactic gamma–ray sky is dominated by two classes of sources: Gamma– Ray Bursts (GRBs) and radio loud active galactic nuclei whose jets are pointing at us (blazars). We believe that the radiation we receive from them originates from the transformation of bulk relativistic energy into random energy. Although the mechanisms to produce, collimate and accelerate the jets in these sources ...
متن کاملThe spectrum of the Broad Line Region and the high-energy emission of powerful blazars
High-energy emission (from the X-ray through the γ-ray band) of Flat Spectrum Radio Quasars is widely associated with the inverse Compton (IC) scattering of ambient photons, produced either by the accretion disk or by the Broad Line Region, by highenergy electrons in a relativistic jet. In the modelling of the IC spectrum one usually adopts a simple black body approximation for the external rad...
