The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

The propagation of gamma-rays over cosmological distances is the subject of extensive
theoretical and observational research at GeV and TeV energies. The mean free path of …

Abstract 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 …

We offer a survey of the matter-antimatter evolution within the primordial Universe. While the
origin of the tiny matter-antimatter asymmetry has remained one of the big questions in …

Measuring the magnetic field in cosmic filaments reveals how the Universe is magnetized
and the process that magnetized it. Using the Rotation Measures (RM) at 144 MHz from the …

This review of scaling theories of magnetohydrodynamic (MHD) turbulence aims to put the
developments of the last few years in the context of the canonical time line (from Kolmogorov …

We simulate the evolution of relativistic eletrons injected into the medium of a small galaxy
cluster by a central radio galaxy, studying how the initial jet power affects the dispersal and …

On the largest scales, galaxies are pulled together by gravity to form clusters, which are
connected by filaments making a web-like pattern. Radio emission is predicted from this …

We present detailed forecasts for the constraints on the characteristics of primordial
magnetic fields (PMFs) generated prior to recombination that will be obtained with the …

We present initial results from the Polarization Sky Survey of the Universe's Magnetism
(POSSUM), analysing 22 817 Faraday rotation measures (RMs) with median uncertainties of …
