Einstein probe: exploring the changing ray universe

Abstract
Thanks to the continuous use of wide field of view astronomical monitoring equipment, time domain astrophysics has entered the golden age of multi band and multi messenger observation. The X-ray universe is dynamic, with abundant high-energy flash sources, some of which are still mysterious in nature, and more are waiting to be discovered. The Einstein probe (EP) is a space X-ray astronomical satellite, which is planned to be launched at the end of 2022. It aims to monitor the little known soft X-ray band with high sensitivity. It is expected to find a large number of X-ray temporary sources inside and outside the Milky way, including rare ones with important scientific value, and monitor the time-varying characteristics of known sources. This report will introduce the scientific drive of EP, the technology used, the scientific capability and the scientific prospect in the field of time domain astronomy. EP is a space satellite project led by the Chinese Academy of Sciences and jointly participated by ESA and MPE.
