Science Results from 10 Years of CALET on the International Space Station

ORAL

Abstract

The Calorimetric Electron Telescope (CALET) continues to collect excellent data after ten years of operation on the International Space Station. CALET, which started operations in October 2015, was designed to measure the combined spectra of the highest-energy electrons and positrons through the TeV energy decade to search for nearby sources and/or signatures of dark matter processes, and measure the spectra of the hadronic components up to PeV total energies. Secondary science goals include measuring the relative abundances of the ultra-heavy galactic cosmic rays (UHGCRs) (up to Z=44) that probe the processes involved in cosmic-ray acceleration and propagation in the galaxy. The CALET calorimeter is also sensitive to GeV-energy gamma rays and is being used to study persistent and transient astrophysical sources, the galactic center excess, and to search for signatures of dark matter. The CALET Gamma-Ray Burst Monitor (CGBM) also monitors the sky for X-ray and soft gamma-ray transients, including in connection with gravitational wave events. Additionally, CALET has made many significant space weather measurements, having demonstrated sensitivity to events in observations of variability in the flux of geomagnetically trapped particles, especially using on-board measurements of precipitating electrons.

*CALET is supported by JAXA in Japan, ASI in Italy, and NASA in the US.
