Research Abstract

Fermi Gamma-ray Space Telescope which we have contributed to its development launched in June, 2008, and it enables us to monitor the gamma-ray emission from jets of supermassive black holes continuously. We have also observed with KANATA optical telescope in Hiroshima University simultaneously with Fermi. As a result, we discovered the gamma-ray emission from jets or lobes of radio galaxies and the correlation time variability between the gamma-ray flux and optical polarization. These gave us new insights into jet structures. We published these results with press conferences and papers.
