Spiral galaxies, including the Milky Way, have large-scale magnetic fields with significant
energy densities. The dominant theory attributes these magnetic fields to a large-scale …

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 …

Diffuse radio emission has been detected in a considerable number of galaxy clusters and
groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic …

Magnetic fields are a dynamically important component of the turbulent interstellar medium
(ISM) of star-forming galaxies. These magnetic fields are due to a dynamo action, which is a …

Magnetic fields in several astrophysical objects are amplified and maintained by a dynamo
mechanism, which is the conversion of the turbulent kinetic energy to magnetic energy. A …

Turbulence in a conducting plasma can amplify seed magnetic fields in what is known as the
turbulent, or small-scale, dynamo. The associated growth rate and emergent magnetic-field …

Understanding magnetic-field generation and amplification in turbulent plasma is essential
to account for observations of magnetic fields in the universe. A theoretical framework …

Pulsars can act as an excellent probe of the Milky Way magnetic field. The average strength
of the Galactic magnetic field component parallel to the line of sight can be estimated as …

Magnetic fields in galaxies and galaxy clusters are amplified from a very weak seed value to
the observed G strengths by the turbulent dynamo. The seed magnetic field can be of …

Magnetic fields grow quickly, even at early cosmological times, suggesting the action of a
small-scale dynamo (SSD) in the interstellar medium (ISM) of galaxies. Many studies have …
