Preface: Origins of cosmic rays
Abstract
Last decade was generous on discoveries in astrophysics of cosmic rays, thanks to new experimental techniques and technological breakthroughs integrated into the instruments launched to the top of the atmosphere and into space. Among them PAMELA, Fermi-LAT, AMS-02, and more recently launched CALET, DAMPE, and ISS-CREAM. Ground-based gamma-ray telescopes, such as H.E.S.S., MAGIC, and VERITAS, and water Cherenkov detector HAWC, proved to be able to probe cosmic ray fluxes in distant locations. Besides, we witnessed the birth of gravitational wave astronomy (LIGO and Virgo) and the first astrophysical neutrinos detected by IceCube. Meanwhile, instruments designed and built using the technology of 1970s are also continuing to surprise us. Here we are talking about the Voyager 1, 2 spacecraft launched in 1977. The former entered interstellar space in 2012, exactly 100 years after the discovery of cosmic rays by Viktor Hess; the latter is taking a longer path.
