Discovered: Energetic hot wind from low-luminosity active galactic nucleus

Supermassive black holes in the universe swallow gas around them. The infalling gas is called black hole accretion flow. In a study published in Nature Astronomy, the group led by Prof. YUAN Feng at Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, together with the group led by Prof. LI Zhiyuan at Nanjing University, found direct evidence for the existence of an energetic hot wind launched from the hot accretion flow onto a weakly accreting supermassive black hole, re...
