ULTRASAT The Ultraviolet Transient Astronomy Satellite

摘要

ULTRASAT is a scientific mini-satellite carrying a telescope with an unprecedentedly large field of view (210 squared degrees) observing in the ultraviolet (220-280 nm,UV),that is proposed by an Israeli/US collaboration to be constructed and launched to near geostationary orbit by 2020/21. The wide field of view and the advanced UV detectors will enable the discovery and monitoring of transient sources within a cosmic volume 300 times larger than that of the most powerful UV satellite to date, GALEX, thus revolutionizing our understanding of the transient UV universe.
