The flat-spectrum radio quasar 3C 345 from the high to the low emission state
M. Berton, N. H. Liao, G. La Mura +17
We report simultaneous observations at different energy bands in radio, optical, UV, X-rays and rays of the flat-spectrum radio-quasar 3C 345. We built the light curve of the s…
Relativistic plasmas in AGN jets - From synchrotron radiation to -ray emission
Giovanni La Mura, Giovanni Busetto, Stefano Ciroi +5
Relativistic jets of plasma are a key ingredient of many types of Active Galactic Nuclei (AGN). Today we know that AGNs are powered by the accretion of inter stellar material into…
Broad-band properties of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We report about recent updates of broad-band properties of radio-loud narrow-line Seyfert 1 galaxies.
Multiwavelength survey of a sample of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We report on a multiwavelength survey of a sample of 42 flat-spectrum radio-loud narrow-line Seyfert 1 galaxies (RLNLS1s). This is the largest known sample of this type of active g…
Optical counterparts of undetermined type -ray Active Galactic Nuclei with blazar-like Spectral Energy Distributions
G. La Mura, G. Chiaro, S. Ciroi +4
During its first four years of scientific observations, the Fermi Large Area Telescope (Fermi-LAT) detected 3033 -ray sources above a 4 significance level. Although most of t…
Parent population of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies
Marco Berton, Luigi Foschini, Stefano Ciroi +7
Flat-spectrum radio-loud Narrow-Line Seyfert 1 galaxies (NLS1s) are a recently discovered class of -ray emitting Active Galactic Nuclei (AGN), that exhibit some blazar-like prop…
Properties of flat-spectrum radio-loud Narrow-Line Seyfert 1 Galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We have conducted a multiwavelength survey of 42 radio loud narrow-1ine Seyfert 1 galaxies (RLNLS1s), selected by searching among all the known sources of this type and omitting th…
Optical Emission Lines and the X-Ray Properties of Type 1 Seyfert Galaxies
G. La Mura, S. Ciroi, V. Cracco +3
In this contribution we report on the study of the optical emission lines and X-ray spectra of a sample of Type 1 AGNs, collected at the Sloan Digital Sky Survey database and obser…
Emission line profiles and X-ray observations of Broad and Narrow Line Seyfert 1 Galaxies
G. La Mura, S. Ciroi, V. Cracco +3
Narrow Line Seyfert 1 galaxies represent a distinct category in the larger family of Type 1 Active Galactic Nuclei. The occurrence of emission line profiles not broader than 2000 k…
