Constraints on the magnetic field in the hadronic scenario for the origin of the radio halo in the A1795 galaxy cluster
P. Marchegiani, V. Vacca, F. Loi +2
The radio halo in the cool-core galaxy cluster, A1795, has recently been proposed to be of hadronic origin, because it extends on megaparsec scales, where no turbulence is expected…
The First High Frequency Technosignature Search Survey with the Sardinia Radio Telescope
Lorenzo Manunza, Alice Vendrame, Luca Pizzuto +30
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz. In this paper, we extend the sear…
NuSTAR Observations of Abell 665 and 2146: Constraints on Non-Thermal Emission
Randall Rojas Bolivar, Daniel Wik, Ayşegül Tümer +11
Observations from past missions such as RXTE and Beppo-SAX suggested the presence of inverse Compton (IC) scattering at hard X-ray energies within the intracluster medium of some m…
A joint XMM-NuSTAR observation of the galaxy cluster Abell 523: constraints on Inverse Compton emission
F. Cova, F. Gastaldello, D. R. Wik +17
We present the results of a joint XMM-Newton and NuSTAR observation (200 ks) of the galaxy cluster Abell 523 at . The peculiar morphology of the cluster radio halo and its…
Untangling cosmic magnetic fields: Faraday tomography at metre wavelengths with LOFAR
Shane P. O'Sullivan, M. Brüggen, C. L. Van Eck +7
The technique of Faraday tomography is a key tool for the study of magnetised plasmas in the new era of broadband radio polarisation observations. In particular, observations at me…
The Galaxy in circular polarization: all-sky radio prediction, detection strategy, and the charge of the leptonic cosmic rays
Torsten A. Enßlin, Sebastian Hutschenreuter, Valentina Vacca +1
The diffuse Galactic synchrotron emission should exhibit a low level of diffuse circular polarization (CP) due to the circular motions of the emitting relativistic electrons. This…
