Aims. A long timeline kinematic study of the archetypal CSO OQ 208 sheds light on the physical properties of the most compact radio sources. Methods. Archival data from the VLBA at…
The faint source population at 15.7 GHz - I. The radio properties
I. H. Whittam, J. M. Riley, D. A. Green +6
We have studied a sample of 296 faint (> 0.5 mJy) radio sources selected from an area of the Tenth Cambridge (10C) survey at 15.7 GHz in the Lockman Hole. By matching this catalogu…
Radio observations of Planck clusters
Ruta Kale
Recently, a number of new galaxy clusters have been detected by the ESA-Planck satellite, the South Pole Telescope and the Atacama Cosmology Telescope using the Sunyaev-Zeldovich e…
Rise and Fall of Radio Halos in Simulated Merging Galaxy Clusters
Julius Donnert, Klaus Dolag, Gianfranco Brunetti +1
We present the first high resolution MHD simulation of cosmic-ray electron reacceleration by turbulence in cluster mergers. We use an idealised model for cluster mergers, combined…
Properties of gas clumps and gas clumping factor in the intra cluster medium
F. Vazza, D. Eckert, A. Simionescu +2
The spatial distribution of gas matter inside galaxy clusters is not completely smooth, but may host gas clumps associated with substructures. These overdense gas substructures are…
The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
Low frequency follow up of radio halos and relics in the GMRT Radio Halo Cluster Survey
Tiziana Venturi, Simona Giacintucci, Daniele Dallacasa +4
We performed GMRT low frequency observations of the radio halos, relics and new candidates belonging to the GMRT Radio Halo Cluster Sample first observed at 610 MHz. High sensitivi…
Radio Continuum Surveys with Square Kilometre Array Pathfinders
Ray P. Norris, J. Afonso, D. Bacon +48
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation radio telescopes and upgrades are already being built around the world. These include APERTIF (T…
Chandra observations of dying radio sources in galaxy clusters
M. Murgia, M. Markevitch, F. Govoni +4
The dying radio sources represent a very interesting and largely unexplored stage of the active galactic nucleus (AGN) evolution. They are considered to be very rare, and almost al…
Spectral Energy Distributions of low-luminosity radio galaxies at z~1-3: a high-z view of the host/AGN connection
Ranieri D. Baldi, Marco Chiaberge, Alessandro Capetti +3
We study the Spectral Energy Distributions, SEDs, (from FUV to MIR bands) of the first sizeable sample of 34 low-luminosity radio galaxies at high redshifts, selected in the COSMOS…
Thermal and non-thermal traces of AGN feedback: results from cosmological AMR simulations
F. Vazza, M. Brueggen, C. Gheller
We investigate the observable effects of feedback from Active Galactic Nuclei (AGN) on non-thermal components of the intracluster medium (ICM). We have modelled feedback from AGN i…
The Planck-ATCA Co-eval Observations (PACO) project: the spectrally-selected sample
Anna Bonaldi, Laura Bonavera, Marcella Massardi +1
The Planck-ATCA Co-eval Observations (PACO) have provided multi-frequency (5-40 GHz) flux density measurements of complete samples of Australia Telescope 20 GHz (AT20G) radio sourc…
Radio Halos in future surveys in the radio continuum
R. Cassano, G. Brunetti, Ray P. Norris +3
Giant radio halos (RH) are Mpc-scale synchrotron sources detected in a significant fraction of massive and merging galaxy clusters.Their statistical properties can be used to discr…
Compact sources in the Bologna Complete Sample: high resolution VLA observations and optical data
E. Liuzzo, S. Buttiglione, G. Giovannini +3
Among radio galaxies, compact sources are a class of objects not yet well understood, and most of them cannot be included in classical populations of compact radio sources (flat sp…
Comparisons of Cosmological MHD Galaxy Cluster Simulations to Radio Observations
Hao Xu, Federica Govoni, Matteo Murgia +6
Radio observations of galaxy clusters show that there are G magnetic fields permeating the intra-cluster medium (ICM), but it is hard to accurately constrain the strength and st…
Extended soft X-ray emission in 3CR radio galaxies at z < 0.3: High Excitation and Broad Line Galaxies
B. Balmaverde, A. Capetti, P. Grandi +11
We analyze Chandra observations of diffuse soft X-ray emission associated with a complete sample of 3CR radio galaxies at z < 0.3. In this paper we focus on the properties of the s…
A 20 GHz bright sample for δ > +72°: I. Catalogue
S. Righini, E. Carretti, R. Ricci +9
During 2010-2011, the Medicina 32-m dish hosted the 7-feed 18-26.5 GHz receiver built for the Sardinia Radio Telescope, with the goal to perform its commissioning. This opportunity…
Planck intermediate results. VIII. Filaments between interacting clusters
Planck Collaboration, P. A. R. Ade, N. Aghanim +208
About half of the baryons of the Universe are expected to be in the form of filaments of hot and low density intergalactic medium. Most of these baryons remain undetected even by t…
