On the amplification of magnetic fields in cosmic filaments and galaxy clusters
F. Vazza, M. Brüggen, C. Gheller +1
The amplification of primordial magnetic fields via a small-scale turbulent dynamo during structure formation might be able to explain the observed magnetic fields in galaxy cluste…
The stripping of a galaxy group diving into the massive cluster A2142
D. Eckert, S. Molendi, M. Owers +7
Structure formation in the current Universe operates through the accretion of group-scale systems onto massive clusters. The detection and study of such accreting systems is crucia…
A giant radio halo in the cool core cluster CL1821+643
A. Bonafede, H. T. Intema, M. Brüggen +8
Giant radio halos are Mpc-size sources found in some merging galaxy clusters. The synchrotron emitting electrons are thought to be (re)accelerated by plasma turbulence induced by t…
An Efficient Fokker-Planck Solver and its Application to Stochastic Particle Acceleration in Galaxy Clusters
Julius Donnert, Gianfranco Brunetti
Particle acceleration by turbulence plays a role in many astrophysical environments. The non- linear evolution of the underlying cosmic-ray spectrum is complex and can be described…
Local Group dSph radio survey with ATCA (III): Constraints on Particle Dark Matter
M. Regis, S. Colafrancesco, S. Profumo +3
We performed a deep search for radio synchrotron emissions induced by weakly interacting massive particles (WIMPs) annihilation or decay in six dwarf spheroidal (dSph) galaxies of…
The VIMOS Public Extragalactic Redshift Survey - Searching for Cosmic Voids
D. Micheletti, A. Iovino, A. J. Hawken +46
The characterisation of cosmic voids gives unique information about the large-scale distribution of galaxies, their evolution and the cosmological model. We identify and characteri…
The VIMOS Public Extragalactic Redshift Survey (VIPERS). Measuring nonlinear galaxy bias at z~0.8
C. Di Porto, E. Branchini, J. Bel +46
We use the first release of the VImos Public Extragalactic Redshift Survey of galaxies (VIPERS) of ~50,000 objects to measure the biasing relation between galaxies and mass in the…
Deep radio observations of the radio halo of the bullet cluster 1E 0657-55.8
Timothy W. Shimwell, Shea Brown, Ilana J. Feain +3
We present deep 1.1-3.1 GHz Australia Telescope Compact Array observations of the radio halo of the bullet cluster, 1E 0657-55.8. In comparison to existing images of this radio hal…
Testing Secondary Models for the Origin of Radio Mini-Halos in Galaxy Clusters
John ZuHone, Gianfranco Brunetti, Simona Giacintucci +1
We present an MHD simulation of the emergence of a radio minihalo in a galaxy cluster core in a "secondary" model, where the source of the synchrotron-emitting electrons is hadroni…
Mapping the particle acceleration in the cool core of the galaxy cluster RX J1720.1+2638
Simona Giacintucci, Maxim Markevitch, Gianfranco Brunetti +4
We present new deep, high-resolution radio images of the diffuse minihalo in the cool core of the galaxy cluster RX J1720.1+2638. The images have been obtained with the Giant Metre…
Discovery of large-scale diffuse radio emission and of a new galaxy cluster in the surroundings of MACSJ0520.7-1328
G. Macario, H. T. Intema, C. Ferrari +11
We report the discovery of large-scale diffuse radio emission South-East of the galaxy cluster MACS J0520.7-1328, detected through high sensitivity Giant Metrewave Radio Telescope…
Cosmic rays in galaxy clusters and their non-thermal emission
G. Brunetti, T. W. Jones
Radio observations prove the existence of relativistic particles and magnetic field associated with the intra-cluster-medium (ICM) through the presence of extended synchrotron emis…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): A quiescent formation of massive red-sequence galaxies over the past 9 Gyr
A. Fritz, M. Scodeggio, O. Ilbert +46
We explore the evolution of the Colour-Magnitude Relation (CMR) and Luminosity Function (LF) at 0.4<z<1.3 from the VIMOS Public Extragalactic Redshift Survey (VIPERS) using ~45,000…
Simulations of cosmic rays in large-scale structures: numerical and physical effects
Franco Vazza, Claudio Gheller, Marcus Brüggen
Non-thermal (relativistic) particles are injected into the cosmos by structure formation shock waves, active galactic nuclei and stellar explosions. We present a suite of unigrid c…
The VIMOS Public Extragalactic Redshift Survey (VIPERS). Never mind the gaps: comparing techniques to restore homogeneous sky coverage
O. Cucciati, B. R. Granett, E. Branchini +28
[Abridged] Non-uniform sampling and gaps in sky coverage are common in galaxy redshift surveys, but these effects can degrade galaxy counts-in-cells and density estimates. We carry…
