A research team led by Prof. WANG Junxian from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) revealed a clumped, multi-component eclipsing absorber in a study of X-ray occultation events in the active galaxy NGC 6814. The results were published in Monthly Notices of the Royal Astronomical Society on Aug. 23. Active galactic nuclei have strong X-ray emission originating in a compact region near the supermassive black hole, the so-called corona region.
