High energy cosmic rays
I review here some of the physics we are learning and expect to learn in the near future through the observation of cosmic rays. The study of cosmic rays involves a combination of data from accelerators, ground arrays, atmospheric fluorescence detectors and balloon and satellite experiments. I will discuss the data of the Pierre Auger Observatory, PAMELA, ATIC and FST among other experiments.
متن کاملVery High Energy Cosmic Rays and Their Interactions
The investigation of very high energy cosmic rays and their interactions are inherently connected subjects of astroparticle physics. On one hand the understanding of cosmic ray interactions is needed to study the flux, acceleration and propagation of cosmic rays. For example, the high energy cosmic ray flux can only be measured by linking secondary particle cascades observed in detectors or the...
متن کاملOn the Origin of Very High Energy Cosmic Rays
We discuss the most recent developments in our understanding of the acceleration and propagation of cosmic rays up to the highest energies. In particular we specialize our discussion to three issues: 1) developments in the theory of particle acceleration at shock waves; 2) the transition from galactic to extragalactic cosmic rays; 3) implications of up-to-date observations for the origin of ult...
متن کاملUltra High Energy Cosmic Rays
The origin of the particles in the highest energy end of the cosmic ray spectrum is discussed in the context of the wider problem of the origin of the whole cosmic radiation as observed at the Earth. In particular we focus our attention on the acceleration problem and on the transition from galactic to extragalactic cosmic rays.
متن کاملUltra High Energy Cosmic Rays
The current status of Ultra High Energy Cosmic Rays (UHECR) is reviewed, with emphasis given to theoretical interpretation of the observed events. The galactic and extragalactic origin, in case of astrophysical sources of UHE particles, have the problems either with acceleration to the observed energies or with the fluxes and spectra. Topological defects can naturally produce particles with ene...
