Simulations of primary beam effects on the cosmic bispectrum phase observed with the Hydrogen Epoch of Reionization Array
N. Charles, G. Bernardi, H. L. Bester +9
The 21~cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation. The main difficulty in measuring the 21 cm signal is the presen…
Exploring the relation between turbulent velocity and density fluctuations in the stratified intracluster medium
Marco Simonte, Franco Vazza, Fabrizio Brighenti +2
The dynamics of the intracluster medium (ICM) is affected by turbulence driven by several processes, such as mergers, accretion and feedback from active galactic nuclei. X-ray surf…
A LOFAR view into the stormy environment of the galaxy cluster 2A0335+096
A. Ignesti, G. Brunetti, T. Shimwell +10
Radio observations represent a powerful probe of the physics occurring in the intracluster medium (ICM) because they trace the relativistic cosmic rays in the cluster magnetic fiel…
Cosmic backgrounds from the radio to the far-infrared: recent results and perspectives from cosmological and astrophysical surveys
Carlo Burigana, Elia Sefano Battistelli, Laura Bonavera +8
Cosmological and astrophysical surveys in various wavebands, in particular from the radio to the far-infrared, offer a unique view of the universe's properties and the formation an…
MeerKAT view of the diffuse radio sources in Abell 3667 and their interactions with the thermal plasma
F. de Gasperin, L. Rudnick, A. Finoguenov +11
During their lifetime, galaxy clusters grow through the accretion of matter from the filaments of the large scale structure and from mergers with other clusters. These mergers rele…

We present deep and high fidelity images of the merging galaxy cluster Abell 2256 at low frequencies, using the upgraded Giant Metrewave Radio Telescope (uGMRT) and LOw-Frequency A…
Turbulent magnetic fields in the merging galaxy cluster MACS J0717.5+3745: polarization analysis
K. Rajpurohit, M. Hoeft, D. Wittor +20
We present wideband polarimetric observations, obtained with the Karl G. Jansky Very Large Array (VLA), of the merging galaxy cluster MACS J0717.5+3745, which hosts one of the most…
Deep Chandra observations of merging galaxy cluster ZwCl 2341+0000
X. Zhang, A. Simionescu, C. Stuardi +9
Knowledge of X-ray shock and radio relic connection in merging galaxy clusters has been greatly extended in terms of both observation and theory over the last decade. ZwCl 2341+000…
SKA-Low Intensity Mapping Pathfinder Updates: Deeper 21 cm Power Spectrum Limits from Improved Analysis Frameworks
Nichole Barry, Gianni Bernardi, Bradley Greig +2
The Square Kilometre Array (SKA) is a planned radio interferometer of unprecedented scale that will revolutionize low-frequency radio astronomy when completed. In particular, one o…
Euclid preparation: XIX. Impact of magnification on photometric galaxy clustering
F. Lepori, I. Tutusaus, C. Viglione +183
We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated s…
A LOFAR-uGMRT spectral index study of distant radio halos
G. Di Gennaro, R. J. van Weeren, R. Cassano +9
Context. Radio halos are megaparsec-scale diffuse radio sources{ mostly} located at the centres of merging galaxy clusters. The common mechanism invoked to explain their origin is…
First Results from HERA Phase I: Upper Limits on the Epoch of Reionization 21 cm Power Spectrum
The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +74
We report upper-limits on the Epoch of Reionization (EoR) 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data ( hours of integration) from Phase I of the…
A search for candidate strongly-lensed dusty galaxies in the Planck satellite catalogues
Tiziana Trombetti, Carlo Burigana, Matteo Bonato +5
The Planck sub-mm surveys detected the brightest strongly gravitationally lensed dusty galaxies in the sky. The combination of their extreme gravitational flux boosting and image s…
The Evolutionary Map of the Universe Pilot Survey
Ray P. Norris, Joshua Marvil, J. D. Collier +45
We present the data and initial results from the first Pilot Survey of the Evolutionary Map of the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array Pa…
Stacking the Synchrotron Cosmic Web with FIGARO
