| Research Abstract |
In order to clarify the mechanism of high-energy gamma-ray emission from celestial active objects, we analyzed the gamma-ray data observed by the LAT detector onboard the Fermi Gamma-ray Space Telescope.
Especially Galactic objects, like X-ray binaries, supernova remnants and pulsar nebula are the main targets of this study. We detected the gamma-ray signal from an X-ray binary and a pulsar nebula, PSR1259-63/SS2883, when it passed the periastron in 2010 December. We also gave upper limits on gamma-ray emission from seven X-ray binaries. Other objects are under analysis.
