Particle physics with cosmic accelerators

Physical Review D, 1986
We discuss the atmospheric showers initiated by 1--${10}^{4}$-TeV photons emitted by cosmic accelerators such as Cygnus X-3. The direction and characteristic time structure of the radiation from such sources can be used to tag a beam of known composition (\ensuremath{\gamma} rays) with well-understood interactions (QED) with the target atmosphere.

Physics of Cosmic Radiation Fields

Radiation Protection Dosimetry, 1999
This paper glances at the knowledge of composition and energy spectra of galactic cosmic rays and briefly discusses the mechanism of solar modulation and of shielding against these particles by the earth's magnetic field. A short review of the properties of solar particle events is given, in which particles emitted from the sun enter the atmosphere ...

On the cosmic limits of physical laws

Astrophysics and Space Science, 1996
Views on the completeness of the general theory of relativity are reviewed. An approach to a generalization of the theory based on a modification of the principle of inertia is outlined.

From Accelerators to Cosmic Ray Physics

AIP Conference Proceedings, 2011
In the present paper, we discuss the interplay between Collider Physics and Cosmic Ray Physics. In particular we outline the impact of present and future collider measurements and searches in the understanding of several aspects, related with Cosmic Ray Physics problematics.
