Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that contribute to a substantial energy density of cosmic rays (CRs). Hence, clusters are expected to be luminous gamma-ray emitters since they also act as energy reservoirs for additional CR sources, such as active galactic nuclei and supernova-driven galactic winds. To detect the gamma-ray emission from CR interactions with the ambient cluster gas… Expand

Constraints on the gamma-ray emission from the cluster-scale AGN outburst in the Hydra A galaxy cluster
These are the first limits on gamma-ray emission ever presented for galaxy clusters hosting cluster scale AGN outbursts, and the non-detection of Hydra A in gamma-rays has important implications on the particle populations and physical conditions inside the bubbles in this system. Expand
Cosmic Rays in Galaxy Clusters and Their Interaction with Magnetic Fields
Cosmic rays can be accelerated in galaxy clusters by different mechanisms and remain confined in the cluster volume accumulating for cosmological times. This component is expected to generateExpand
Search for cosmic-ray induced gamma-ray emission in Galaxy Clusters
Current theories predict relativistic hadronic particle populations in clusters of galaxies in addition to the already observed relativistic leptons. In these scenarios hadronic interactions giveExpand
Constraining the efficiency of cosmic ray acceleration by cluster shocks
We study the acceleration of cosmic rays by collisionless structure formation shocks with ENZO grid simulations. Data from the FERMI satellite enable the use of galaxy clusters as a testbed forExpand
Deep observation of the NGC 1275 region with MAGIC: search of diffuse γ-ray emission from cosmic rays in the Perseus cluster
Clusters of galaxies are expected to be reservoirs of cosmic rays (CRs) that should produce diffuse gamma-ray emission due to their hadronic interactions with the intra-cluster medium. The nearbyExpand
High-energy gamma-ray and neutrino backgrounds from clusters of galaxies and radio constraints
Cosmic-ray protons accumulate for cosmological times in clusters of galaxies as their typical radiative and diffusive escape times are longer than the Hubble time. Their hadronic interactions withExpand
Constraints on Cosmic Rays, Magnetic Fields, and Dark Matter from Gamma-Ray Observations of the Coma Cluster of Galaxies with VERITAS and Fermi

Non-thermal radio emission from cosmic-ray electrons in the vicinity of merging galaxy clusters is an important tracer of cluster merger activity, and is the result of complex physical processes thatExpand
New Limits on Gamma-Ray Emission from Galaxy Clusters
Galaxy clusters are predicted to produce γ-rays through cosmic ray interactions and/or dark matter annihilation, potentially detectable by the Fermi Large Area Telescope (Fermi-LAT). We present aExpand

Cangaroo-III search for TeV gamma rays from two clusters of galaxies
Because accretion and merger shocks in clusters of galaxies may accelerate particles to high energies, clusters are candidate sites for the origin of ultra-high-energy (UHE) cosmic rays. A predictionExpand
The detection of diffuse radio emission associated with clusters of galaxies indicates populations of relativistic leptons infusing the intracluster medium. Those electrons and positrons are eitherExpand
Magnetic fields and cosmic rays in clusters of galaxies
We argue that the observed correlation between the radio luminosity and the thermal X-ray luminosity of radio emitting galaxy clusters implies that the radio emission is due to secondary electronsExpand
