The appearance of active galactic nuclei (AGN) depends so strongly on orientation that our
current classification schemes are dominated by random pointing directions instead of more …

▪ Abstract A large collective effort to study the variability of active galactic nuclei (AGN) over
the past decade has led to a number of fundamental results on radio-quiet AGN and blazars …

We collect data at well-sampled frequencies from the radio to the γ-ray range for the
following three complete samples of blazars: the Slew survey, the 1-Jy samples of BL Lacs …

The phenomenology of γ‐ray bright blazars can be accounted for by a sequence in the
source power and intensity of the diffuse radiation field surrounding the relativistic jet …

An Analysis of the Synchrotron Self-Compton Model for the Multi--Wave Band Spect ADS Classic
is now deprecated. It will be completely retired in October 2019. This page will automatically …

The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy
threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi …

We assess non-thermal Comptonization models for the high-energy emission of the EGRET
blazar sources. We argue that the copious γ-ray radiation originates from a region that is …

We study the entire sample of quasars detected above 100 MeV (by the EGRET instrument),
on board CGRO. We find that the γ-ray luminosity correlates better with the radio luminosity …

The central engine causing the production of jets in radio sources may work intermittently,
accelerating shells of plasma with different mass, energy and velocity. Faster but later shells …

Blazars are the most violent steady/recurrent sources of high-energy gamma-ray emission in
the known Universe. They are prominent emitters of electromagnetic radiation throughout …
