Peering Into the Extended X-ray Emission on Megaparsec Scale in 3C 187
A. Paggi, F. Massaro, H. A. Pena-Herazo +7
Context. The diffuse X-ray emission surrounding radio galaxies is generally interpreted either as due to inverse Compton scattering of non-thermal radio-emitting electrons on the C…
The Coma cluster at LOFAR frequencies I: insights into particle acceleration mechanisms in the radio bridge
A. Bonafede, G. Brunetti, F. Vazza +18
Radio synchrotron emission from the bridges of low-density gas connecting galaxy clusters and groups is a challenge for particle acceleration processes. In this work, we analyse th…
Extended X-ray emission around FR II radio galaxies: hotspots, lobes and galaxy clusters
Ana Jimenez-Gallardo, Francesco Massaro, Alessandro Paggi +20
We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge catalog (3CR) Chandra Snapshot Survey wit…
ClG 0217+70: A massive merging galaxy cluster with a large radio halo and relics
X. Zhang, A. Simionescu, J. S. Kaastra +7
We present an analysis of archival Chandra data of the merging galaxy cluster ClG 0217+70. The Fe XXV He X-ray emission line is clearly visible in the 25 ks observation, allowin…
The 3CR extragalactic survey at high redshift
A. Jimenez-Gallardo, F. Massaro, M. A. Prieto +13
We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with during Cycle 20 in the redshift range between 1.5 and 2…
Discovering the most elusive radio relic in the sky: Diffuse Shock Acceleration caught in the act?
Nicola T. Locatelli, Kamlesh Rajpurohit, Franco Vazza +9
The origin of radio relics is usually explained via diffusive shock acceleration (DSA) or re-acceleration of electrons at/from merger shocks in galaxy clusters. The case of acceler…
The LOFAR view of intergalactic magnetic fields with giant radio galaxies
C. Stuardi, S. P. O'Sullivan, A. Bonafede +8
Giant radio galaxies (GRGs) are physically large radio sources that extend well beyond their host galaxy environment. Their polarization properties are affected by the poorly const…
New constraints on the magnetization of the cosmic web using LOFAR Faraday rotation observations
S. P. O'Sullivan, M. Brüggen, F. Vazza +11
Measuring the properties of extragalactic magnetic fields through the effect of Faraday rotation provides a means to understand the origin and evolution of cosmic magnetism. Here w…
