| Outline of Final Research Achievements |
In order to investigate the physical processes working during the emission gravitational waves (GW) and the origin of the astrophysical GW sources, we searched for X and gamma-ray counterparts of GW events detected by LIGO including GW150914, the black hole merger event with the first GW detection, using the MAXI all-sky X-ray monitor and the CALET gamma-ray burst monitor on the International Space Station, obtaining upper limits for X/gamma radiation. Furthermore, we conducted concept study of WF-MAXI mission that can efficiently detect transient X-ray emission from GW events with its Large-solid angle Soft X-ray Camera. We developed and built a laboratory model, and we proposed this mission as an ISS payload. In addition we observed astrophysical sources involved in GW emission such as neutron stars, black holes, and gamma-ray bursts using various missions, MAXI, Swift, Fermi, and CALET.
