A review of galactic magnetic fields is given with emphasis on simple analytical solutions of relevant equations and detailed comparison with observations. It is shown that mean-field dynamo theory, in its simplest form, is in a remarkably good agreement with observations of galactic magnetic fields. It is argued that the disc-halo connection can play crucial role in the nonlinear evolution of regular magnetic fields in spiral galaxies by driving flux of magnetic helicity from the disc, thus… Expand

Magnetic Fields in the Universe
The origin and maintenance of large scale magnetic fields in the Universe is discussed. A popular idea is that cosmic batteries generate seed magnetic fields which were amplified by magneticExpand
Progress in the Global Modeling of the Galactic Magnetic Field
We discuss the global modeling of the properties of the Galactic Magnetic Field (GMF). Several improvements and variations of the model of the GMF from Jansson & Farrar (2012) (JF12) are investigatedExpand
Magnetizing the universe
The origin of cosmic magnetism is an issue of fundamental importance in astrophysics. We review here some of the ideas of how large scale magnetic fields in the universe, particularly in galaxies andExpand
Course 4 Astrophysical dynamos
Publisher Summary This chapter reviews that the dynamo theory is relatively young: the ability of a flow of conducting fluid to maintain magnetic field was conjectured 90 years ago. Both physical andExpand
Non-linear dynamo action and disc-halo interaction in disc galaxies
We have developed a mathematical model which reproduces a broad range of observables in several galaxies, within the same physical framework. We present an observationally constrained model of massExpand

The origin of the structure of large-scale magnetic fields in disc galaxies
The large-scale magnetic fields observed in spiral disc galaxies are often thought to result from dynamo action in the disc plane. However, the increasing importance of Faraday depolarization alongExpand
Evolution of magnetic fields in galaxies and future observational tests with the Square Kilometre Array
Aims. In the context of models of galaxy formation and evolution, we investigate the cosmological evolution of large- and small-scale magnetic fields inside galaxies. Methods. We use the dynamoExpand
Asymptotic solutions for mean-field slab dynamos
We discuss asymptotic solutions of the kinematic -dynamo in a thin disc (slab) surrounded by an electric insulator. Focusing upon the strong dynamo regime, in which the dynamo number satisfies , weExpand
Importance of magnetic helicity in dynamos
Magnetic helicity is nearly conserved and its evolution equation provides a dynamical feedback on the alpha effect that is distinct from the conventional algebraic alpha quenching. The seriousness ofExpand


Galactic Magnetism: Recent developments and perspectives
▪ Abstract We discuss current observational and theoretical knowledge of magnetic fields, especially the large-scale structure in the disks and halos of spiral galaxies. Among other topics, weExpand
A Critical Review of Galactic Dynamos
▪ Abstract I present the general picture of how galactic magnetic fields grow in disks according to the alpha-Omega dynamo theory. Emphasis is placed on following the lines of force during the dynamoExpand
Dynamos in discs and halos of galaxies
Linear and nonlinear dynamo models are investigated for a galactic disc embedded in a halo, assuming a relatively strong magnetic diffusivity and a non-vanishing α effect in the halo. The halo isExpand
Structure of the Galactic Magnetic Field
Faraday rotation measurements have shown that there is a basic order in the galactic magnetic field which can be fitted by simple models. The data also indicate the presence of irregularities inExpand
Magnetic Fields in Young Galaxies
We have studied the fate of initial magnetic fields in the hot halo gas out of which the visible parts of galaxies form, using three-dimensional numerical MHD-experiments. The halo gas undergoesExpand
Accretion and galactic dynamos
We show that radial flows (directed either inward or outward) suppress mean-field dynamo action in a thin disc. Under conditions typical of spiral galaxies, the reduction in the growth rate of theExpand
