CALET Gamm-ray observation results are featured in on-line version of The Astrophysical Journal

Last Updated: November 2, 2018


The CALorimetric Electron Telescope (CALET) is being operated to observe three kinds of high-energy cosmic-rays: electrons (including positrons), gamma rays, and protons and atomic nuclei.

An American scientific journal, "The Astrophysical Journal," featured in its issue of September 5, 2018 in on-line version (IF: 8.561) an article that summarizes the CALET's capabilities demonstrated by the CALET Science Team during two-year on-orbit observation of gamma rays in the high energy range between 1 GeV and 10 TeV.

The article presents the observation results regarding major gamma-ray sources such as Vela, Geminga and Crab. These observation results coincide significantly with those delivered by the "Fermi" gamma-ray observation satellite. This may evidence the reliability of the CALET observation data. Gamma-ray observation is an important method for studying the origins of cosmic rays.
