Summary

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. The low background and large effective area in the hard X-ray band also make it good at observing diffuse hard X-ray emissions, such as many TeV sources which will be newly found in 2030s.
