Description
The CALorimetric Electron Telescope (CALET) is a high-energy astroparticle physics experiment in operation on the International Space Station (ISS) since 2015 with excellent and continuous performance. Designed to measure the spectra of electrons+positrons up to 20 TeV (and gamma rays up to 10 TeV), CALET is searching for possible nearby sources of high-energy electrons and dark matter signatures. Unexpected deviations from a power-law were observed not only for electrons (around 1 TeV), but also in the spectra of proton, helium, and heavier cosmic nuclei. With a precise measurement of their charge, cosmic nuclei can be identified and their spectra measured up to the PeV energy scale, contributing to the study of galactic cosmic-ray acceleration and propagation. CALET also measures the relative abundances of ultra-heavy galactic cosmic rays (UHGRC) above atomic number Z=28 (nickel) and past Z=40 (zirconium).
Here, we present the highlights of the CALET latest science results stemming from almost 10 years of spectral observations of cosmic leptons, hadrons, and photons. Some recent results on the observations of solar modulation will also be included, together with the study of space-weather phenomena, X-ray and soft gamma-ray transients, and searches of electromagnetic counterparts of LIGO/Virgo gravitational wave events. Characterization of on-orbit performance, with approximately 20 million events above 10 GeV recorded per month, will be reported.
