X-ray Astronomy and Einstein Probe

The Einstein Probe(EP) is an international mission initiated and led by the Chinese Academy of Sciences(CAS) to observe high-energy transients, a type of astronomical objects whose temporal dynamics helps us understand the evolution of the universe and some fundamental questions in basic physics. Expected to fly at the end of 2022, it will close a long-existing gap in X-ray astronomy. Dr. JIN Chichuan, a researcher of the EP team has the story.
