Optical photon-counting observation of the Crab pulsar with Kanata telescope using prototype IMONY
Takeshi Nakamori, Kazuaki Hashiyama, Rin Sato +14
We have developed an optical photon-counting imaging system, IMONY, as an instrument for short-scale time-domain astronomy. In this study, we utilized a Geiger avalanche photodiode…
