| Outline of Final Research Achievements |
In this project, in order to realize a genuine X-ray and gamma-ray polarization observation, we planned to develop a SGD detector onboard ASTRO-H satellite and conduct observations. In addition, we planned to proceed gamma-ray observations by Fermi satellite and optical polarization observations with Kanata telescope in Hiroshima university to study celestial objects with jet which show a polarization. Unfortunately, X-ray polarization mission was cancelled, and ASTRO-H/Hitomi satellite was lost just after the launch, and thus we could not realize a multi-wavelength polarization observation. However, we could obtain many results from gamma-ray and optical polarization observations of jet objects. Also, we could show a SGD capability of gamma-ray polarization measurements by observing a Crab nebula.
