Radio VLBA polarization and multi-band monitoring of the high-redshift quasar S5 0836+710 during a high activity period
M. Orienti, F. D'Ammando, M. Giroletti +3
We report on results of a multi-band monitoring campaign from radio to gamma rays of the high-redshift flat spectrum radio quasar S5 0836+710 during a high activity period detected…
Particle re-acceleration and Faraday-complex structures in the RXC J1314.4-2515 galaxy cluster
C. Stuardi, A. Bonafede, D. Wittor +9
Radio relics are sites of electron (re)acceleration in merging galaxy clusters but the mechanism of acceleration and the topology of the magnetic field in and near relics are yet t…
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…
Particle acceleration in a nearby galaxy cluster pair: the role of cluster dynamics
A. Botteon, R. Cassano, D. Eckert +17
Diffuse radio emission associated with the intra-cluster medium (ICM) is observed in a number of merging galaxy clusters. It is currently believed that in mergers a fraction of the…
Growth and disruption in the Lyra complex
S. Clavico, S. De Grandi, S. Ghizzardi +16
Nearby clusters of galaxies, z<0.1, are cosmic structures still under formation. Understanding the thermodynamic properties of merging clusters can provide crucial information on h…
A discovery of young radio sources in the cores of giant radio galaxies selected at hard X-rays
G. Bruni, F. Panessa, L. Bassani +9
Giant Radio Galaxies (GRG) are the largest single entities in the Universe, having a projected linear size exceeding 0.7 Mpc, which implies that they are also quite old objects. Th…
Probing restarting activity in hard X-ray selected giant radio galaxies
G. Bruni, F. Ursini, F. Panessa +13
With their sizes larger than 0.7 Mpc, Giant Radio Galaxies (GRGs) are the largest individual objects in the Universe. To date, the reason why they reach such enormous extensions is…
The space density of z>4 blazars
Alessandro Caccianiga, Alberto Moretti, Silvia Belladitta +9
High redshift blazars are an important class of Active Galactic Nuclei (AGN) that can provide an independent estimate of the supermassive black-hole mass function in high redshift…
