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 ()…
Swift data hint at a binary Super Massive Black Hole candidate at sub-parsec separation
P. Severgnini, C. Cicone, R. Della Ceca +10
Dual/binary Supermassive Black Hole (SMBH) systems are the inevitable consequence of the current Lambda Cold Dark Matter cosmological paradigm. In this context, we discuss here the…
SDSSJ143244.91+301435.3 at VLBI: a compact radio galaxy in a narrow-line Seyfert 1
A. Caccianiga, D. Dallacasa, S. Anton +4
We present VLBI observations, carried out with the European Very Long Baseline Interferometry Network (EVN), of SDSSJ143244.91+301435.3, a radio-loud narrow-line Seyfert 1 (RLNLS1)…
The structure of the X-ray absorber in Mrk 915 revealed by Swift
P. Severgnini, L. Ballo, V. Braito +5
In this paper we present the results obtained with a monitoring programme (23 days long) performed with Swift-XRT on the local Seyfert galaxy Mrk 915. The light-curve analysis show…
Mining the XRT archive to probe the X-ray absorber structure in the AGN population
L. Ballo, P. Severgnini, A. Moretti +6
One of the key ingredients of the Unified Model of Active Galactic Nuclei (AGN) is the presence of a torus-like optically thick medium composed by dust and gas around the putative…
