Particle astrophysics

Definition

Particle astrophysics is the study of fundamental particles travelling through space, particularly those that reach the Earth. These cosmic rays include photons, protons, alpha particles and neutrinos. Some of these decay to other particles in the atmosphere, while neutrinos can pass through the entire Earth without being absorbed.

    Early results from the COSINE-100 experiment—designed to test a much-debated claim of the detection of a dark-matter signal—show no indications of dark matter, providing evidence against the previous claim.

    Using data from the IceCube telescope, a study presents the first attempt at obtaining geophysical information about Earth’s internal structure from the flux of neutrinos that pass through it.

    • Véronique Van Elewyck

    An ultrahigh-energy neutrino event detected with the IceCube detector in Antarctica, simultaneous and co-spatial with a multi-wavelength outburst of a blazar about 3 billion light years away, points unambiguously to lepto-hadronic cooling mechanisms in jetted active galactic nuclei.

    Active galactic nuclei are firm favourites to be revealed as the source of cosmic rays, but solid evidence has proven elusive. A model taking both local and global nuclei propagation into account may help to close the deal.
