Reasons and benefits of using JAXA Supercomputer System
In high-energy astronomy research using large amounts of scientific satellite data, the computational time required for routine data processing is often the rate-limiting factor in research. If the computation time can be reduced by using a supercomputer, more time can be spent on scientific considerations and research progress can be made.
Achievements of the Year
Wide-field image synthesis (deconvolution) was performed for each pointing on about 10 years of data acquired by the BAT instrument on NASA's Swift satellite, and computed light-curves for about 100 objects.
