Extragalactic cosmic rays and the galactic magnetic field

Astrophysics and Space Science, 1973
The origin and behavior of cosmic rays in the Galaxy depend crucially upon whether the galactic magnetic field has a closed topology, as does the field of earth, or whether a major fraction of the lines of force connect into extragalactic space. This paper examines the structure of a galactic field that opens initially into intergalactic space and ...

The role of magnetic fields in extragalactic astronomy

Astrophysics and Space Science, 1981
The evidence is reviewed for a universal magnetic field of strength 10−9–10−8G; it has been extended to include the diffuse fields of galactic clusters and the extensive magnetic halos of spiral galaxies. Some likely effects of the universal fieldB 0 are as follows: (1) As suggested previously,B 0 is coupled to protogalaxies and evolves into magnetic ...

Intergalactic Magnetic Fields and Faraday Rotation of Extragalactic Radio Sources

Publications of the Astronomical Society of Japan, 1979
Abstract This paper reexamines our earlier statistical analyses of rotation measures RM and redshifts z of extragalactic radio sources. Absolute magnitudes of RM of 97 sources at high galactic latitudes, |b|35°, are shown to increase with z.

Time Evolution of Primordial Magnetic Fields and Present Day Extragalactic Magnetism

2014
The topic of the present thesis is the time evolution of Primordial Magnetic Fields which have been generated in the Early Universe. Assuming this so-called Cosmological Scenario of magnetogenesis to be true, it is shown in the following that this would account for the present day Extragalactic Magnetic Fields.
