IT is important to decide whether or not the main sources of the cosmic ray particles are external to our galaxy. An external source seems, at first sight, to be established by the observed isotropy of the cosmic rays incident on the earth. But it has been claimed by a number of authors that this isotropy is simply a consequence of a magnetic field assumed to exist in interstellar space. The basis for this claim is that a single particle of energy η and charge e is deflected through an… 
Gamma rays and the origin of cosmic rays
Summary and conclusionsIt has been pointed out that cosmic γ-rays have something to say about the origin of cosmic-ray particles. Although the statistical precision of the data and the directional
The origin of galactic magnetic fields
Galactic magnetic fields and cosmic rays are tightly bound up together. The fact that the energy density of cosmic rays in the local region of the Galaxy is approximately the same order of magnitude
The strength of galactic magnetic fields
THE magnitudes of galactic magnetic fields are usually estimated from measurements of the radio synchroton emission arising from acceleration of cosmic-ray electrons in the magnetic field. To
The sources of cosmic rays
Studies of the mass composition of cosmic rays as a function of energy by the MACRO collaboration support the view that the well known steepening of the overall cosmic ray spectrum at 3*1015 eV is
The origin and anisotropy of high energy cosmic rays
The evidence for the anisotropy of cosmic rays from 10(^11)eV to 10(^20)eV is considered in detail from both a Galactic and extragalactic viewpoint and placed in astrophysical context. The importance
Origin of cosmic rays: Galactic models with halo
Many years ago physical and radio-astronomical arguments and data led to the assumption that cosmic rays in the Galaxy (and probably in other galaxies) fill a more or less extended halo, but are not
Diffusion of the highest energy cosmic rays from Virgo
The origin of the predominant particle component of cosmic rays is still undecided although at ‘low’ energies (E∼109–1010 eV) γ-ray data provide circumstantial evidence in favour of an origin in
Gamma-ray evidence for cosmic-ray sources
The origin of cosmic-rays is one of the long-standing problems in astro physics. In recent years, strong evidence has been found that certain classes of object contain and are able to accelerate
THE ACCELERATION OF COSMIC RAYS BY SHOCK WAVES
The problem of the origin of galactic cosmic rays is a particularly difficult one despite the fact that rather detailed measurements of the properties of cosmic rays can be made, at least in the
On the origin of cosmic rays and the value of fundamental length
It is suggested that the physical mechanism responsible for the acceleration of cosmic rays is due to the stochastic (or fluctuational) structure of space-time at small distances. A method of
