The Fermi-LAT view of young radio sources
F. D'Ammando, M. Orienti, M. Giroletti
Compact Symmetric Objects (CSO) are considered to be the young version of Fanaroff-Riley type I and type II radio galaxies, with typical sizes smaller than 1 kpc and ages of the or…
High-energy properties of the high-redshift flat spectrum radio quasar PKS 2149-306
F. D'Ammando, M. Orienti
We investigate the gamma-ray and X-ray properties of the flat spectrum radio quasar PKS 2149-306 at redshift z = 2.345. A strong gamma-ray flare from this source was detected by th…
The multi-faceted synergy between Swift and Fermi in radio-loud AGN studies
F. D'Ammando
Since its launch in 2008 June, the Fermi Gamma-ray Space Telescope has opened a new era in high-energy astrophysics. The unprecedented sensitivity, angular resolution and effective…
The connection between radio and high energy emission in black hole powered systems in the SKA era
M. Giroletti, M. Orienti, F. D'Ammando +9
Strong evidence exists for a highly significant correlation between the radio flux density and gamma-ray energy flux in blazars revealed by Fermi. However, there are central issues…
The innermost regions of relativistic jets and their magnetic fields in radio-loud Active Galactic Nuclei
I. Donnarumma, I. Agudo, L. Costamante +17
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
