Multi-frequency databases for AGN investigation - Results and perspectives
Giovanni La Mura, Marco Berton, Sina Chen +5
Active Galactic Nuclei (AGNs) are characterized by emission of radiation over more than 10 orders of magnitude in frequency. Therefore, the execution of extensive surveys of the sk…
Extended narrow-line region in Seyfert galaxies
Enrico Congiu, Marcella Contini, Stefano Ciroi +7
We present our recent results about the extended narrow-line region (ENLR) of two nearby Seyfert 2 galaxies (IC 5063 and NGC 7212) obtained by modelling the observed line profiles…
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…
High resolution spectroscopy of the extended narrow-line region of IC 5063 and NGC 7212
E. Congiu, M. Contini, S. Ciroi +6
We studied the properties of the gas of the extended narrow line region (ENLR) of two Seyfert 2 galaxies: IC 5063 and NGC 7212. We analysed high resolution spectra to investigate h…
Fermi observations of the LIGO event GW170104
Melissa Pesce-Rollins, Nicola Omodei, Dan Kocevski +3
We present the \emph{Fermi} Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) observations of the LIGO binary black hole merger (BBH) event GW170104. No candidate electr…
3FGLzoo. Classifying 3FGL Unassociated Fermi-LAT Gamma-ray Sources by Artificial Neural Networks
David Salvetti, Graziano Chiaro, Giovanni La Mura +1
In its first four years of operation, the Fermi Large Area Telescope (LAT) detected 3033 -ray emitting sources. In the Fermi-LAT Third Source Catalogue (3FGL) about 50% of the s…
An orientation-based unification of young jetted AGN: the case of 3C 286
M. Berton, L. Foschini, A. Caccianiga +6
In recent years, the old paradigm according to which only high-mass black holes can launch powerful relativistic jets in active galactic nuclei (AGN) has begun to crumble. The disc…
Cosmic-ray electron+positron spectrum from 7 GeV to 2 TeV with the Fermi Large Area Telescope
LAT Collaboration, S. Abdollahi, M. Ackermann +97
We present a measurement of the cosmic-ray electron+positron spectrum between 7 GeV and 2 TeV performed with almost seven years of data collected with the Fermi Large Area Telescop…
The intrinsic Baldwin effect in broad Balmer lines of six long-term monitored AGNs
Nemanja Rakic, Giovanni La Mura, Dragana Ilic +4
We investigate the intrinsic Baldwin effect (Beff) of the broad H and H emission lines for six Type 1 active galactic nuclei (AGNs) with different broad line characteristics:…
The Fermi Galactic Center GeV Excess and Implications for Dark Matter
LAT Collaboration
The region around the Galactic center (GC) is now well established to be brighter at energies of a few GeV than expected from conventional models of diffuse gamma-ray emission and…
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…
