Magnetic fields and relativistic electrons fill entire galaxy cluster
A. Botteon, R. J. van Weeren, G. Brunetti +12
The hot plasma within merging galaxy clusters is predicted to be filled with shocks and turbulence that may convert part of their kinetic energy into relativistic electrons and mag…
The Planck clusters in the LOFAR sky. III. LoTSS-DR2: Dynamic states and density fluctuations of the intracluster medium
X. Zhang, A. Simionescu, F. Gastaldello +19
The footprint of LoTSS-DR2 covers 309 PSZ2 galaxy clusters, 83 of which host a radio halo and 26 host a radio relic(s). It provides us an excellent opportunity to statistically stu…
Galaxy clusters enveloped by vast volumes of relativistic electrons
V. Cuciti, F. de Gasperin, M. Brueggen +12
The central regions of galaxy clusters are permeated by magnetic fields and filled with relativistic electrons. When clusters merge, the magnetic fields are amplified and relativis…
Abell 1033: Radio halo and gently reenergized tail at 54 MHz
H. W. Edler, F. de Gasperin, G. Brunetti +7
Abell 1033 is a merging galaxy cluster of moderate mass (). It hosts a broad variety of diffuse radio sources linked to different astroph…
Diffuse radio emission from non-Planck galaxy clusters in the LoTSS-DR2 fields
D. N. Hoang, M. Brüggen, A. Botteon +17
The presence of large-scale magnetic fields and ultra-relativistic electrons in the intra-cluster medium (ICM) is confirmed through the detection of diffuse radio synchrotron sourc…
Particle re-acceleration and diffuse radio sources in the galaxy cluster Abell 1550
T. Pasini, H. W. Edler, M. Brüggen +13
We study diffuse radio emission in the galaxy cluster A1550, with the aim of constraining particle re-acceleration in the intra-cluster medium. We exploit observations at four diff…
The Coma cluster at LOFAR frequencies II: the halo, relic, and a new accretion relic
A. Bonafede, G. Brunetti, L. Rudnick +26
We present LOw Frequency ARray observations of the Coma cluster field at 144\,MHz. The cluster hosts one of the most famous radio halos, a relic, and a low surface-brightness bridg…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
The Planck clusters in the LOFAR sky. I. LoTSS-DR2: new detections and sample overview
A. Botteon, T. W. Shimwell, R. Cassano +23
Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM) and manifest themselves as diffuse sources of synchrotron emission observable at radio wavelength…
