Wide-band x-ray observatory for the time domain astronomy era: CHRONOS

Abstract

Chronos is a X-ray observatory concept capable of "hour-level" follow up observations of transient alerts in 2030s' multi-messenger astronomy, with 0.3-40+ keV wide X-ray band-width and 250-300 nm ultra-violet (UV) coverage. The mission has a good hard X-ray imaging spectroscopy with > 9 ′ field of view, the soft X-ray imager with > 30 ′ field of view, and the UV imager with > 7 • field of view. Aiming at launch in mid-2030s, the mission is designed to provide wide-band spectroscopy of time dependent high-energy phenomena.
