- Self-introduction
- I mainly study an optical and near-infrared astronomy. The main target is a relativistic jet which is ejected from the center of active galactic nuclei (AGNs). AGNs are located on the center of galaxies. I observe the jets and other objects by using Kanata telescope at Higashi-Hiroshima Observatory and radio telescopes.
Recently, I'm belonging to J-GEM (Japanese Collaboration for Gravitational-Wave Electro-Magnetic Follow-up) to identify and observe the gravitational-wave counterpart. Furthermore, I configure and maintain a HinOTORI 50-cm optical telescope at Ali in Tibet, China.
