Progress in high-energy cosmic ray physics
(Elsevier Science, 2018-01)
We review some of the recent progress in our knowledge about high-energy cosmic rays, with an emphasis on the interpretation of the different observational results. We discuss the effects that are relevant to shape the ...
Upper limits on the total cosmic-ray luminosity of individual sources
(Iop Publishing, 2014-07)
In this paper, upper limits on the total luminosity of ultra-high-energy cosmic-rays (UHECR) (E > 10^18 eV) are determined for five individual sources. The upper limit on the integral flux of GeV-TeV gamma-rays is used to ...
Magnetic diffusion and interaction effects on ultrahigh energy cosmic rays: Protons and nuclei
(American Physical Society, 2021-09)
The flux of ultrahigh energy cosmic rays reaching the Earth is affected by the interactions with the cosmic radiation backgrounds as well as with the magnetic fields that are present along their trajectories. We combine ...
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 ...
Active galactic nuclei: sources for ultra high energy cosmic rays
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst, in the radio galaxy Cen A which is pushed up in energy by the shock of a relativistic jet. ...
