Composition of Anomalous Cosmic Rays and Other Heliospheric Ions
Interstellar pickup ions accelerated by the termination shock of the solar wind dominate the anomalous cosmic-ray (ACR) intensities observed by the Voyager spacecraft in the outer heliosphere. Using a twodimensional acceleration and propagation model, we derive the relative abundances of these interstellar ACRs and determine the mass dependence of the injection/acceleration efficiency for the d...
متن کاملFractional diffusion of cosmic rays
We consider the propagation of galactic cosmic rays under assumption that the interstellar medium is a fractal one. An anomalous diffusion equation in terms of fractional derivatives is used to describe of cosmic ray propagation. The anomaly in used model results from large free paths (" Lévy flights ") of particles between galactic inhomogeneities and long time a particle stays in a trap. An a...
متن کاملNon-linear Quantum Mechanics and High Energy Cosmic Rays
We point out that the presence of energetic cosmic rays above the GZK cutoff may be explained by fundamental non-linearities in quantum mechanics at the Planck level.
متن کاملSpatial Origin of Galactic Cosmic Rays in Diffusion Models: II- Exotic Primary Cosmic Rays
In a companion paper, we investigated the question of the spatial origin of the cosmic rays detected in the Solar neighborhood, in the case of standard sources located in the Galactic disk. There are some reasons to believe that there may also be a large number of sources located in the halo, for example if the Galactic dark matter is made of supersymmetric particles or if Primordial Black Hole...
متن کاملLong-Term Cosmic Ray Modulation by Heliospheric Pa- rameters: Non-linear Relations
The heliospheric modulation strength is a good parameter for the long-term modulation of cosmic rays in the neutron monitor energy range. Here we study an empirical relation between the modulation strength and the global heliospheric parameters: the heliospheric current sheet tilt angle, the open solar magnetic flux and the global IMF polarity. The suggested relation closely reproduces the meas...
