Outline of Final Research Achievements

The MAXI (Monitor of All-sky X-ray Image) nova-alert system to discover transient objects, such as X-ray novae, has been improved. As a result, the system can trigger on low flux variations near detection limits of GSC (Gas Slit Camera) detectors in realtime, and 11 X-ray transients including three black hole candidates were newly discovered. We have also established the method of the power spectrum analysis to investigate short-term variations during scan observations, and confirmed the state transition of black hole candidates from the power spectrum analysis. In addition, we developed a nova-alert system for SSC (Solid-state Slit Camera) data.
