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…

We summarize the second radio synchrotron background workshop, which took place June 15-17, 2022 in Barolo, Italy. This meeting was convened because available measurements of the d…
A Stochastic Theory of the Hierarchical Clustering III. The Non-universality and Non-stationarity of the Halo Mass Function
A. Lapi, T. Ronconi, L. Danese
In the framework of the stochastic theory for hierarchical clustering, we investigate the time-dependent solutions of the Fokker-Planck equation describing the statistics of dark m…
Deep low-frequency radio observations of Abell 2256 II: The ultra-steep spectrum radio halo
K. Rajpurohit, E. Osinga, M. Brienza +17
We present the first detailed analysis of the radio halo in the merging galaxy cluster Abell 2256 using the LOFAR, uGMRT, and VLA. These observations combined with archival X-ray d…
The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28
E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31
Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…
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…
Magnetic field evolution in cosmic filaments with LOFAR data
E. Carretti, S. O'Sullivan, V. Vacca +4
Measuring the magnetic field in cosmic filaments reveals how the Universe is magnetised and the process that magnetised it. Using the Rotation Measures (RM) at 144-MHz from the LoT…
Exploring the cosmological synergy between galaxy cluster and cosmic void number counts
Davide Pelliciari, Sofia Contarini, Federico Marulli +4
Galaxy clusters and cosmic voids, the most extreme objects of our Universe in terms of mass and size, trace two opposite sides of the large-scale matter density field. By studying…
Improved Constraints on the 21 cm EoR Power Spectrum and the X-Ray Heating of the IGM with HERA Phase I Observations
The HERA Collaboration, Zara Abdurashidova, Tyrone Adams +92
We report the most sensitive upper limits to date on the 21 cm epoch of reionization power spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization…
Impact of instrument and data characteristics in the interferometric reconstruction of the 21 cm power spectrum
Adélie Gorce, Samskruthi Ganjam, Adrian Liu +75
Combining the visibilities measured by an interferometer to form a cosmological power spectrum is a complicated process. In a delay-based analysis, the mapping between instrumental…
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…
Galaxy-galaxy lensing in the VOICE deep survey

The multi-band photometry of the VOICE imaging data, overlapping with 4.9 deg of the Chandra Deep Field South (CDFS) area, enables both shape measurement and photometric redshi…
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…
The detection of cluster magnetic fields via radio source depolarisation
E. Osinga, R. J. van Weeren, F. Andrade-Santos +7
It has been well established that galaxy clusters have magnetic fields. The exact properties and origin of these magnetic fields are still uncertain even though these fields play a…
Using the polarization properties of double radio relics to probe the turbulent compression scenario
C. Stuardi, A. Bonafede, K. Rajpurohit +5
Radio relics are Mpc-size synchrotron sources located in the outskirts of some merging galaxy clusters. Binary-merging systems with favorable orientation may host two almost symmet…
