| Outline of Final Research Achievements |
Galactic diffuse gamma rays are the main background for the dark matter searches near the Galactic center. We have improved uncertainties of the galactic diffuse background by verifying the modeling the interstellar medium using dust radiance, opacity and temperature data and identifying several undetected gamma-ray objects by our image restoration software. In parallel, we have improved the crosstalk problem of the novel photon sensor for the next generation gamma-ray instrument, CTA. We found further improvement may be possible by reducing delayed crosstalk. We also successfully developed integrated circuits to provers signals from dense photon sensor and verified the performance by test observations using prototype telescope.
