CENTAURUS A: THE EXTRAGALACTIC SOURCE OF COSMIC RAYS WITH ENERGIES ABOVE THE KNEE
(IOP PUBLISHING LTDBRISTOL, 2012)
The origin of cosmic rays at all energies is still uncertain. In this paper, we present and explore an astrophysical scenario to produce cosmic rays with energy ranging from below 10(15) to 3 x 10(20) eV. We show here that ...
Magnetic diffusion effects on the Ultra-High Energy Cosmic Ray spectrum and composition
(Iop Publishing, 2013-09)
We discuss the effects of diffusion of high energy cosmic rays in turbulent extra-galactic magnetic fields. We find an approximate expression for the low energy suppression of the spectrum of the different mass components ...
A scenario for the Galactic cosmic rays between the knee and the second-knee
(IOP Publishing, 2019-03-07)
We perform a fit to measurements of the cosmic ray spectrum in the energy range between 10 15 eV and 10 18 eV using data from the TALE, Tunka and Auger experiments. We also fit the data on the depth of shower maximum, X ...
Implications of gamma-ray observations on proton models of ultrahigh energy cosmic rays
(American Physical Society, 2016-09)
The origin of ultrahigh energy cosmic rays (UHECR) is still unknown. However, great progress has been achieved in past years due to the good quality and large statistics in experimental data collected by the current ...
An upper limit on the cosmic-ray luminosity of individual sources from gamma-ray observations
(Iop Publishing, 2013-12)
Different types of extragalactic objects are known to produce TeV gamma-rays. Some of these objects are the most probable candidates to accelerate cosmic rays up to 1020 eV. It is very well known that gamma-rays can be ...
