Time Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...

متن کاملCosmic Ray Antiprotons
Interstellar (IS) cosmic rays consist mainly of protons with a smaller admixture of heavier nuclei. Antiprotons (p’s) occur at an abundance of 10 of p’s. These energetic particles, kinetic energy K > 10 MeV, are Galactic in origin, not to be confused with the much denser solar wind plasma, with much lower K. The relative element abundances in cosmic rays (CRs) indicate that CR primaries are ion...
متن کاملCosmic ray strangelets
Searching for strangelets in cosmic rays may be the best way to test the possible stability of strange quark matter. I review calculations of the astrophysical strangelet flux in the GV–TV rigidity range, which will be investigated from the Alpha Magnetic Spectrometer (AMS-02) on the International Space Station, and discuss the merits of strangelets as ultra-high energy cosmic rays at EeV–ZeV e...
متن کاملCosmic Ray Astrophysics
The problem of the origin of cosmic rays is considered in an astronomical context and the current observational situation summarised. The evidence for acceleration in supernova remnants is critically examined.
