Very high energy gamma-ray emission of NGC 1275 and 3c382 and the possible activity nature of the Seyfert Galaxies
... Galaxy clusters have been consider as sources of TeV γ- rays emitted by high-energy protons and electrons accel- erated by large scale structure formation shocks, galactic winds, or active galactic nuclei. The Perseus ...

Continuum reverberation mapping of the accretion disks in two Seyfert 1 galaxies
... We present optical continuum lags for two Seyfert 1 galaxies, MCG + 08-11-011 and NGC 2617, using monitoring data from a reverberation mapping campaign carried out in 2014. Our light curves span the ugriz fi ...

A radio and infrared investigation of Seyfert galaxies in the local universe
... Lawrence (1987) is a thorough, early review of AGN unification in general. There have been several, slightly differing (in most cases) models (Blanford & Königl 1979; Wilson 1981, 1982; Pedlar et al. 1985; Wilson ...

Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions
... Before the launch of the Fermi satellite only two classes of AGNs were known to produce these structures and thus to emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical ...

Velocity resolved reverberation mapping of five bright Seyfert 1 galaxies
... The scaling factor f can be determined for an AGN if there is an independent measurement of the black hole mass. Unfortunately, there are few cases where the black hole radius of influence is large enough that either ...
