Genesis, dynamics, and dissipation of turbulent magnetic fields
… indicate that coherent, dynamically important magnetic fields are ubiquitous in the Universe. However, neither the origin problem—what are the physical mechanisms that generate the initial ``seed'' magnetic fields—nor the dynamo problem—how magnetic fields are amplified and sustained by …

Full Mueller imaging: direction dependent corrections in polarimetric radio imaging
Magnetic fields pervade the universe, spanning a multitude of scales from the dipolar field on Earth, to the largest gravitationally bound structures such as galaxy clusters [1]. The magnetic fields play a vital role in the evolution of these astronomical systems. In addition to the multitude of …

EXPANSION AFTER INFLATION AND REHEATING WITH A CHARGED INFLATON
… homogeneous and isotropic as necessitated by cosmic microwave background observations. This patch, however, is also in a cold and non-thermal state. A successful model of an inflationary primordial universe should account for how the universe transitioned from an inflationary to a …

Cio-cio-san no yuutsu: memoirs of magnetogenesis and turbulent dynamo theory
The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions via a thermal battery term in the Induction …

Strong Magnetic Field Effects and Molecular Processes with Applications to White Dwarfs
… transitions of hydrogenlike atoms in external magnetic fields of strength applicable to magnetic white dwarfs, i.e. B < 10<sup>3</sup> megagauss, have been investigated for field-free principal quantum numbers n < 6. Finite proton mass corrections are included. Relativistic corrections are also …
