- 研究成果概要
- This project served to prepare for the scientific analysis of data from the ISS-based cosmic-ray experiment CALET, which for the first time directly measures the TeV-region spectrum of electron cosmic rays. The cosmic ray signatures of nearby astrophysical sources and Dark Matter Annihilation and Decay were studied. Based on these results, methods to distinguish different models or constrain their parameter spaces with CALET data were developed, and CALET’s sensitivity to these signatures evaluated.
The sensitivity of CALET to Dark Matter Annihilation in the Galactic Halo was calculated for several Dark Matter candidates, with the results presented at conferences and published in the Journal of Cosmology and Astroparticle Physics. This study also evaluated the influence of uncertainties on the background spectrum and the cosmic-ray propagation parameters on the expected limits.
To investigate the influence of a nearby supernova remnant (SNR), the spectrum of the nearby Vela SNR was calculated using the numerical calculation program DRAGON, which was extended to include calculation of individual point-sources. The case of decaying Dark Matter has also been studied, showing the potential of CALET to identify decay with at least some direct decay to electrons and positrons.
