Magnetogenesis in Cyclical Universe
Natacha Leite, Petar Pavlović
We propose a simple solution to the magnetogenesis problem based on cyclic cosmology. It is demonstrated that magnetic fields, of sufficient strengths to account for the present ob…
Do Cosmic Rays Heat the Early Intergalactic Medium?
Natacha Leite, Carmelo Evoli, Marta D'Angelo +3
Cosmic rays (CRs) govern the energetics of present-day galaxies and might have also played a pivotal role during the Epoch of Reionization. In particular, energy deposition by low-…
Chiral Magnetohydrodynamic Turbulence
Petar Pavlović, Natacha Leite, Günter Sigl
In this work the influence of the chiral anomaly effect on the evolution of magnetohydrodynamic turbulence was studied. We argue that in the early universe, before the electroweak…
Synchrotron Emission from Dark Matter in Galactic Subhalos. A Look into the Smith Cloud
Natacha Leite, Robin Reuben, Guenter Sigl +2
One of the key predictions of the WIMP paradigm for Dark Matter (DM) is that DM particles can annihilate into charged particles. These annihilations will proceed in e.g. Galactic s…
Modified Magnetohydrodynamics Around the Electroweak Transition
Petar Pavlović, Natacha Leite, Günter Sigl
We analyse solutions of the MHD equations around the electroweak transition taking into account the effects of the chiral anomaly. It is shown that a transition that is not of the…
Chiral Magnetic Effect in Protoneutron Stars and Magnetic Field Spectral Evolution
Günter Sigl, Natacha Leite
We investigate the evolution of the chiral magnetic instability in a protoneutron star and compute the resulting magnetic power and helicity spectra. The instability may act during…
Average Thermal Evolution of the Universe
Natacha Leite, Alex H. Blin
We sketch the average behaviour of the temperatures and densities of the main components of the CDM universe after inflation. It is modelled as a perfect fluid with dark energy…
