Cosmic-void observations reconciled with primordial magnetogenesis [PDF]
Nature Communications, 2023 It has been suggested that the weak magnetic field hosted by the intergalactic medium in cosmic voids could be a relic from the early Universe. However, accepted models of turbulent magnetohydrodynamic decay predict that the present-day strength of ...

MAGNETIC FIELDS IN CLUSTERS OF GALAXIES [PDF]
International Journal of Modern Physics D, 2004 The existence of magnetic fields associated with the intracluster medium in clusters of galaxies is now well established through different methods of analysis. Magnetic fields are investigated in the radio band from studies of the rotation measure of polarized radio galaxies and the synchrotron emission of cluster-wide diffuse sources.

Magnetic fields during galaxy mergers [PDF]
Astronomy & Astrophysics, 2016 Galaxy mergers are expected to play a central role for the evolution of galaxies, and may have a strong impact on their magnetic fields. We present the first grid-based 3D magneto-hydrodynamical simulations investigating the evolution of magnetic fields during merger events. For this purpose, we employ a simplified model considering the merger event of

Influence of Magnetic Fields on the Gas Rotation in the Galaxy NGC 6946
The Astrophysical Journal, 2023 Magnetic fields can play an important role in the energy balance and formation of gas structures in galaxies. However, their dynamical effect on the rotation curve of galaxies is immensely unexplored.

Magnetic fields in galaxies [PDF]
Proceedings of the International Astronomical Union, 2005 AbstractThe origin and evolution of magnetic fields in the Universe is a cosmological problem. Although exotic mechanisms for magneotgenesis cannot be ruled out, galactic magnetic fields could have been seeded by magnetic fields from stars and accretion disks, and must be continuously regenerated due to the ongoing replacement of the interstellar ...

Inflationary and Phase-transitional Primordial Magnetic Fields in Galaxy Clusters
The Astrophysical Journal, 2023 Primordial magnetic fields (PMFs) are possible candidates for explaining the observed magnetic fields in galaxy clusters. Two competing scenarios of primordial magnetogenesis have been discussed in the literature: inflationary and phase-transitional.

Physics Letters B, 2020 Photons may convert to axion-like particles (ALPs) in external magnetic fields. Under certain conditions, this effect should result in irregular features in observed spectra of astrophysical sources.
