Abstract: Precise measurements of the energy spectra of cosmic rays (CRs) show various kinds of features deviating from single power-laws, which give very interesting and important implications on their origin and propagation. Most recently, spectral softenings… read more here.

DOI: 10.1126/science.358.6365.882-c
Abstract: Particle Astrophysics Several cosmic-ray detectors have found more positrons arriving at Earth than expected. Some researchers interpret this as a signature of exotic physics, such as the annihilation of dark matter particles. Others prefer a… read more here.
