Direct Measurement of the Cosmic-Ray Helium Spectrum from 40 GeV to 250 TeV with the Calorimetric Electron Telescope on the International Space Station

O. Adriani, Y. Akaike, K. Asano +77

We present the results of a direct measurement of the cosmic-ray helium spectrum with the CALET instrument in operation on the International Space Station since 2015. The observati…

Detection of a bright burst from the repeating FRB 20201124A at 2 GHz

Sota Ikebe, Kazuhiro Takefuji, Toshio Terasawa +14

We present a detection of a bright burst from FRB 20201124A, which is one of the most active repeating FRBs, based on S-band observations with the 64-m radio telescope at the Usuda…

Monte Carlo Study of Electron and Positron Cosmic-Ray Propagation with the CALET Spectrum

Katsuaki Asano, Yoichi Asaoka, Yosui Akaike +4

Focusing on the electron and positron spectrum measured with CALET, which shows characteristic structures, we calculate flux contributions of cosmic rays escaped from supernova rem…

Enhanced X-ray Emission Coinciding with Giant Radio Pulses from the Crab Pulsar

Teruaki Enoto, Toshio Terasawa, Shota Kisaka +34

Giant radio pulses (GRPs) are sporadic bursts emitted by some pulsars, lasting a few microseconds. GRPs are hundreds to thousands of times brighter than regular pulses from these s…
