Possibility of Systematic Study of Supernova Explosions by Nuclear Imaging Spectroscopy

Abstract: An all-sky monitor with nuclear imaging spectroscopy is a promising tool for the systematic study of supernova explosions. In particular, progenitor scenarios of type-Ia supernovae, which are not yet well understood, can be resolved using light curves in the nuclear gamma-ray band. Here we report an expected result of an all-sky monitor with imaging spectroscopy using electron-tracking Compton camera, which will enable us to observe nuclear gamma-ray lines from type-Ia supernovae.

“…The present Section addresses the extreme case for which the tracking of the electron is so precise that the analyst can use a bijection between the measured observables for a given Compton scatter event and the direction of the incoming photon (one-to-one mapping, Fig. 1 right), in a scheme that is named ETCC (electrontracking Compton camera) [Tanimori et al, 2004[Tanimori et al, , 2015[Tanimori et al, , 2017. We will see that a low-density high-precision active target, such as a gas TPC, is well suited for that purpose.…”

“…In the reconstruction method in particle physics, additional physical parameters that are not used to solve the kinematics are usually needed to suppress such a background. In MeV gamma-ray telescopes using the reconstruction of Compton scattering, residual physical parameters are considered necessary [Tanimori et al, 2017]. We have good examples.…”
