Three component model of cosmic ray spectra from 10 GeV to 100 PeV

Three component model of cosmic ray spectra from 10 GeV to 100 PeV

Aims. A model to describe cosmic ray spectra in the energy region from 10 10 to 10 17 eV is suggested based on the assumption that Galactic cosmic ray flux is a mixture of fluxes accelerated by shocks from nova and supernova of different types. Methods. We analyze recent experimental data on cosmic ray spectra obtained in direct measurements above the atmosphere and data obtained with ground Ex...

Three component model of cosmic ray spectra from 100 GeV up to 100 PeV

Aims. A model to describe cosmic ray spectra in the energy region from 10 11 up to 10 17 eV is suggested. It bases on the preposition that Galactic cosmic ray flux is a mixture of fluxes, accelerated by shocks from nova and supernova explosions of different types. Methods. We analyze recent experimental data on cosmic ray spectra obtained in direct measurements above the atmosphere and data obt...

Cosmic Rays I . The cosmic ray spectrum between 10 4 GeV and 3 10 9 GeV

Based on a conjecture about the diffusion tensor of relativistic particles perpendicular to the magnetic field at a shock, and considering particle drifts, I develop a theory to account for the Cosmic Ray spectrum between 10 GeV and 3 10 GeV. The essential assumption is that the free mean path perpendicular to the magnetic field is independent of energy and has the scale of the thickness of the...

On the Energy Spectra of GeV/TeV Cosmic Ray Leptons

Recent observations of cosmic ray electrons from several instruments have revealed various degrees of deviation in the measured electron energy distribution from a simple power-law, in a form of an excess around 0.1 to 1TeV energies. An even more prominent deviation and excess has been observed in the fraction of cosmic ray positrons around 10 and 100GeV energies. These observations have receiv...
