Paper Abstract

DIOS (Diffuse Intergalactic Oxygen Surveyor) is a small scientific satellite with the main aim of searching warm-hot intergalactic medium using redshifted OVII and OVIII lines. The wide-field spectroscopic capability of DIOS will also bring rich science about the dynamics of cosmic hot plasmas in all spatial scales. The instrument will consist of a 4-stage X-ray telescope and an array of TES microcalorimeters with up to 400 pixels, cooled with mechanical coolers. Hardware development of DIOS and outstanding issues about the payload are described. DIOS will be further developed with international collaboration and will be proposed to the earliest call of JAXA’s small scientific satellite series.
