- Fabio Gargano (INFN)
- Ivan De Mitri (Gran Sasso Science Institute (GSSI) and INFN)
Description
The study of High Energy (HE) and Ultra-High Energy (UHE) cosmic rays offers unique possibilities to probe their acceleration mechanisms and the effects of their propagation with the interstellar/intergalactic medium. The session will be devoted to a review of recent observations of electrons/positrons, protons/antiprotons, and nuclei made by space and ground-based experiments at energies above hundreds of GeV. New techniques or mission concepts will also be discussed.
AMS-02 is a magnetic spectrometer operating on the ISS since May 2011. Its large acceptance and long exposure time allows to measure the fluxes of all the nuclear species in cosmic rays up to Iron. I will discuss the most recent AMS-02 measurements of primary and secondary nuclei in cosmic rays and their possible contribution to the understanding of the CR acceleration and propagation in the galaxy.
The CALorimetric Electron Telescope CALET is collecting science data on the International Space Station since October 2015 with excellent and continuous performance. Energy is measured with a deep homogeneous calorimeter (1.2 nuclear interaction lengths, 27 radiation lengths) preceded by an imaging pre- shower (3 radiation lengths, 1mm granularity) providing tracking and 10$^{-5}$...
The DArk Matter Particle Explorer (DAMPE) is a space mission, promoted by the Chinese Academy of Science with the collaboration of Italian and Swiss scientific institutions. Since December 2015, DAMPE orbits at the altitude of 500 km and collects data regularly. The detector is made of four sub-detectors: top layers of plastic scintillators, a silicon-tungsten tracker converter, a deep BGO...
The cosmic ray all-particles spectrum is a very important result obtained by the NUCLEON space experiment. This spectrum was directly measured up to energies near 500 TeV. The ground-based experiments provide very large statistics but their results depend on applied models. The NUCLEON experiment allows to compare results of direct measurements and data of ground-based experiments. The...
The High Energy cosmic-Radiation Detection (HERD) space mission is now being designed, as a result of an international collaboration
among several chinese and european institutions, to make cosmic ray (CR) direct measurements at the highest possible energies with current technologies.
HERD primary scientific goals include precise measurements of the energy spectra of CR individual species up...
The Pierre Auger Observatory has by now achieved an exposure of order 10^5 km^2 sr yr, exploring about 85% of the sky. In this talk I will review some of the latest results, including the detailed measurements of the features in the cosmic ray spectrum, the inferred mass composition, the tests of hadronic interactions, multimessenger searches and the study of anisotropies in the cosmic ray...
Developed as NASA Astrophysics Probe-class mission, the Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to identify the sources of ultra-high energy cosmic rays (UHECRs) and to observe cosmic neutrinos with full-sky coverage for both of these extreme- energy messengers. POEMMA consists of two spacecraft flying in a loose formation at 525 km altitudes oriented to view a...
