A variety of observations impose upper limits at the nano Gauss level on magnetic fields that
are coherent on inter-galactic scales while blazar observations indicate a lower bound∼ …

Cosmology, high-energy physics and astrophysics are today converging to the study of large
scale magnetic fields. While the experimental evidence for the existence of large scale …

We analytically derive the spectrum of gravitational waves due to magneto-hydrodynamical
turbulence generated by bubble collisions in a first-order phase transition. In contrast to …

The high-temperature plasma above the electroweak scale∼ 100 GeV may have contained
a primordial hypercharge magnetic field whose anomalous coupling to the fermions induces …

A detailed numerical and analytical examination of the evolution of stochastic magnetic
fields between a putative magnetogenesis era at high cosmic temperatures T∼ 100 M e V …

The power spectrum of a homogeneous and isotropic stochastic variable, characterized by a
finite correlation length, does not, in general, vanish on scales larger than the correlation …

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 discuss, using simple analytical models and magnetohydrodynamic (MHD) simulations,
the origin and parameters of turbulence and magnetic fields in galaxy clusters. Any pre …

We perform direct numerical simulations of three-dimensional freely decaying
magnetohydrodynamic turbulence. For helical magnetic fields, an inverse cascade effect is …

In the presence of magnetic helicity, inverse transfer from small to large scales is well known
in magnetohydrodynamic (MHD) turbulence and has applications in astrophysics …
