On the Non-Thermal Energy Content of Cosmic Structures
Galaxies, 2016 (1) Background: the budget of non-thermal energy in galaxy clusters is not well constrained, owing to the observational and theoretical difficulties in studying these diluted plasmas on large scales; (2) Method: we use recent cosmological simulations ...

The universality of the relation between magnetic fields and star formation in galaxies
Astronomy & AstrophysicsContext. The interstellar medium (ISM) is permeated by magnetic fields affecting gas dynamics and star formation. These magnetic fields have been observed to be related to the supernova-driven turbulence. However, whether this scaling is universal across

MAGNETIC FIELDS IN A SAMPLE OF NEARBY SPIRAL GALAXIES [PDF]
The Astrophysical Journal, 2015 Both observations and modeling ofmagnetic fields in the diffuse interstellar gas of spiral galaxies arewell developed, but the theory has been confronted with observations for only a handful of individual galaxies. There is nowsufficient data to consider the statistical properties of galactic magnetic fields.

Can the Dynamo of Spiral-arm Galaxies Be Explained by Anisotropic Conductivity?
The Astrophysical JournalThe possibility of generating a magnetic field by a dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically and experimentally.

MAGNETIC FIELDS IN COSMOLOGICAL SIMULATIONS OF DISK GALAXIES [PDF]
The Astrophysical Journal, 2014 Observationally, magnetic fields reach equipartition with thermal energy and cosmic rays in the interstellar medium of disk galaxies such as the Milky Way. However, thus far cosmological simulations of the formation and evolution of galaxies have usually neglected magnetic fields.

Cosmology with inhomogeneous magnetic fields [PDF]
, 2007 We review spacetime dynamics in the presence of large-scale electromagnetic fields and then consider the effects of the magnetic component on perturbations to a spatially homogeneous and isotropic universe.

Simulations of the Polarized Sky for the SKA: How to Constrain Intracluster Magnetic Fields
Galaxies, 2018 The advent of the Square Kilometer Array (SKA) will have unprecedented impact on the study of magnetic fields in galaxy clusters. This instrument will be able to perform all-sky surveys in polarization, allowing us to build a rotation-measure (RM) grid ...
