X-ray properties of z>4 blazars
L. Ighina, A. Caccianiga, A. Moretti +4
We present the X-ray analysis of the largest flux-limited complete sample of blazar candidates at z>4 selected from the Cosmic Lens All Sky Survey (CLASS). After obtaining a nearly…
Testing the blast-wave AGN feedback scenario in MCG-03-58-007
Mattia Sirressi, Claudia Cicone, Paola Severgnini +7
We report the first Atacama large millimeter/submillimeter array observations of MCG-03-58-007, a local (, this work) AGN ()…
Exploring the Active Galactic Nuclei population with extreme X-ray to optical flux ratios (Fx/Fo >50)
R. Della Ceca, F. J. Carrera, A. Caccianiga +8
The cosmic history of the growth of supermassive black holes in galactic centers parallels that of star-formation in the Universe. However, an important fraction of this growth occ…
A Focused, Hard X-ray Look at Arp 299 with NuSTAR
A. Ptak, A. Hornschemeier, A. Zezas +19
We report on simultaneous observations of the local starburst system Arp 299 with NuSTAR and Chandra, which provides the first resolved images of this galaxy up to energies of ~ 45…
The XMM-Newton Bright Survey sample of absorbed quasars: X-ray and accretion properties
L. Ballo, P. Severgnini, R. Della Ceca +5
Although absorbed quasars are extremely important for our understanding of the energetics of the Universe, the main physical parameters of their central engines are still poorly kn…
SDSSJ143244.91+301435.3: a link between radio-loud narrow-line Seyfert 1 galaxies and compact steep-spectrum radio sources?
A. Caccianiga, S. Antón, L. Ballo +12
We present SDSSJ143244.91+301435.3, a new case of radio-loud narrow line Seyfert 1 (RL NLS1) with a relatively high radio power (P1.4GHz=2.1x10^25 W Hz^-1) and large radioloudness…
