TL;DR: In this paper, the gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies was detected with Fermi/LAT, and they may form an emerging new class of gamma ray active galactic nuclei (AGN).

TL;DR: By developing a new electronic trigger, the threshold of the MAGIC telescope is lowered, revealing a relatively high cutoff energy in the phase-averaged spectrum, which indicates that the emission occurs far out in the magnetosphere, hence excluding the polar-cap scenario as a possible explanation of the measurement.

TL;DR: In this paper, the authors present multi-wavelength data for twelve blazars observed from 2008-2010 as part of an ongoing optical-infrared photometric monitoring project.

TL;DR: In this paper, an X-ray and optical survey of a sample of 17 radio jets in active galactic nuclei performed with Chandra and the Hubble Space Telescope is presented. But the results are biased toward detection at shorter wavelengths, but preferentially it includes beamed sources.

TL;DR: The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week pointing by CGRO, in 1996 January-February.
