About the ISAS X-ray Astronomy Group

The High Energy Astrophysics group is engaged primarily in X-ray astrophysics research through satellite observation. The past three decades have seen an explosion in high-energy astrophysics. We have found X-ray astronomy to be an indispensable tool for understanding our universe, including all classes of astronomical objects, from degenerate stars (white dwarfs, neutron stars and black holes) to galaxies at cosmological distances.

The group is currently involved in the development of the Astro-E2 satellite, a successor to Astro-E. Astro-E2 carries two focal-plane instruments for soft X-ray observations, and one collimated large-area counter array for hard X-ray. A micro-calorimeter array (X-ray Spectrometer) and four identical sets of X-ray CCDs (X-ray Imaging Spectrometers) cover the energy band from 0.5 keV to ~10keV with imaging capability. The hard X-ray detector is a combination of scintillation detectors and silicon PIN detectors which cover the hard X-ray band from 10 keV to 600 keV. It was planned that the Astro-E mission would be able to perform various kinds of observations of a wide variety of X-ray sources with the highest energy resolution and the highest sensitivity over the widest energy range ever.
