Research Abstract

The purpose of this research was to develop X-ray microcalorimetr using magnetic thermometers aiming for the detection of Oxygen emission lines from the warm-hot intergalactic medium. In this development, we succeeded to sense X-rays by metalic magnetic calorimeters firstly in Japan. The operation of magnetic calorimeters in adiabatic demagnetization refrigerators, which are considered to be only refrigeration method in space, were confirmed. Also future detectability of Oxygen lines by a wide field-of-view and high energy-resolution detectors were inspected in our Local Universe simulated by SPH. The CCD cameras onboard Suzaku satellite launched in 2005 achieved the best energy resolution for diffuse emission in Si detectors. We detected Galactic Oxygen emission with Suzaku, and obtained the tightest constraint for the emission from the intergalactic medium.
