Supernovae (SNe) are one of the most energetic explosion events in the universe, with the human detectability not only in electromagnetic waves but also neutrino and possibly gravitational waves. They also play the main role of chemical evolution of the universe. On the other hand, the explosion mechanism in detail is still unclear. One of the difficulties is that they are rather rare events in the local universe. Instead, we can use their remnants (supernova remnants; SNRs) to investigate the mechanism. We will summarize recent X-ray observations of remnants of supernovae which shows us new information on explosion mechanisms. The near future X-ray missions are also introduced.
Prof. Aya Bamba studies X-ray astronomy, especially for thermal and nonthermal properties of Supernova remnants. She achieved the first observational measurement of particle acceleration efficiency on the shocks of supernova remnants. She also works on the development of silicon semiconductor detector for X-ray spectroscopy.
