It is unfortunalty not possible to ask questions any more, due to a large number of spam posts.

You can still read the old questions.

Cosmic rays have been observed over a broad range of energy, up to 10^20 eV. However, due to ubiquitous magnetic fields, no concrete ideas of the acceleration sites of cosmic rays have yet been established.
Because their trajectories are not deflected by magnetic fields, the study of the neutral secondary particles produced in cosmic ray interactions at the source are an indirect but promising way to determine where the observed cosmic rays are accelerated.
