A jet model for the gamma-ray emitting blazar 3C 279
TL;DR: The physical conditions in the gamma-ray-emitting blazar 3C 279 are discussed in this article, where it is proposed that the gamma rays are produced in a relativistic jet via the synchrotron self-Compton mechanism.
Journal ArticleDOI
Spectral Energy Distributions of Hard X-ray selected AGNs in the XMDS Survey

TL;DR: In this article, the spectral energy distributions (SEDs) of a hard X-ray selected sample were derived based on a SED fitting technique, and the authors identified AGN signatures in 83% of the objects.
Journal ArticleDOI
Relativistic bulk motion in active galactic nuclei
TL;DR: In this paper, the evidence for relativistic bulk motion of the emitting plasma in the nuclei of ∼100 radio sources, which include BL Lacertae objects, radio quasars, and radio galaxies, with published VBLI measurements of the core angular dimension and radio flux was discussed.

TL;DR: 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-Stellar Radio Source 3C 279, at a distance of more than 5 billion light-years.
Journal ArticleDOI
The power of relativistic jets is larger than the luminosity of their accretion disks
TL;DR: An analysis of archival observations of a sample of blazars (quasars whose jets point towards Earth) that overcomes previous limitations finds a clear correlation between jet power, as measured through the γ-ray luminosity, and accretion luminosity; this implies that the magnetic field threading the black hole horizon reaches the maximum value sustainable by the accreting matter.
