We report the X-ray analysis of a sample of candidate high-redshift (1<z<2) FRI sources from the sample of Chiaberge et al. (2009), observed in the Chandra COSMOS field (C-COSMOS).…
Complex particle acceleration processes in the hotspots of 3C105 and 3C445
M. Orienti, M. A. Prieto, G. Brunetti +3
We investigate the nature of the broad-band emission associated with the low-power radio hotspots 3C105 South and 3C445 South. Both hotspot regions are resolved in multiple radio/o…
Evidence for AGN Feedback in Galaxy Clusters and Groups
Myriam Gitti, Fabrizio Brighenti, Brian R. McNamara
The current generation of flagship X-ray missions, Chandra and XMM-Newton, has changed our understanding of the so-called "cool core" galaxy clusters and groups. Instead of the ini…
An unlikely radio halo in the low X-ray luminosity galaxy cluster RXC J1514.9-1523
Simona Giacintucci, Daniele Dallacasa, Tiziana Venturi +4
We report the discovery of a giant radio halo in the galaxy cluster RXC J1514.9-1523 at z=0.22 with a relatively low X-ray luminosity, $L_{X \, [0.1-2.4 \rm \, kev]} \sim 7 \times…
The injection and feedback of Cosmic Rays in large-scale structures
F. Vazza, M. Brueggen, C. Gheller +1
We present the numerical implementation of run-time injection of Cosmic Rays energy, their spatial advection and their dynamical feedack on baryonic gas in the cosmological grid co…
The Star Formation Rate Density and Dust Attenuation Evolution over 12 Gyr with the VVDS Surveys
O. Cucciati, L. Tresse, O. Ilbert +15
[Abridged] We investigate the global galaxy evolution over 12 Gyr (0.05<z<4.5), from the star formation rate density (SFRD), combining the VVDS Deep (17.5<=I<=24.0) and Ultra-Deep…
Probing the Off-State of Cluster Giant Radio Halos
Shea Brown, Andrew Emerick, Lawrence Rudnick +1
We derive the best characterization to date of the properties of radio quiescent massive galaxy clusters through a statistical analysis of their average synchrotron emissivity. We…
Gamma-Ray and Parsec-Scale Jet Properties of a Complete Sample of Blazars From the MOJAVE Program
M. L. Lister, M. Aller, H. Aller +142
We investigate the Fermi LAT gamma-ray and 15 GHz VLBA radio properties of a joint gamma-ray- and radio-selected sample of AGNs obtained during the first 11 months of the Fermi mis…
Herschel-ATLAS Galaxy Counts and High Redshift Luminosity Functions: The Formation of Massive Early Type Galaxies
A. Lapi, J. Gonzalez-Nuevo, L. Fan +35
Exploiting the Herschel-ATLAS Science Demonstration Phase (SDP) survey data, we have determined the luminosity functions (LFs) at rest-frame wavelengths of 100 and 250 micron and a…
Turbulence, Reconnection and Cosmic Rays in Galaxy Clusters
A. Lazarian, G. Brunetti
Recent years have been marked by substantial changes in our understanding of magnetic turbulence and magnetic reconnection, which, in its turn induced better understanding of cosmi…
