Astronomers observe Supermassive Black Hole Feeding and Feedback on Sub-Parsec Scales

Black holes are messy eaters
Carbon monoxide (CO; indicating the presence of medium-density molecular gas) is shown in red; atomic carbon (C; indicating the presence of atomic gas) in blue; hydrogen cyanide (HCN; indicating the presence of high density molecular gas) in green; and the hydrogen recombination line (H36α; indicating the presence of ionized gas) in pink. The size of the central dense gas disk (green) is approximately 6 light-years. The plasma outflow travels almost perpendicular to the disk. Credit: ALMA (ESO/NAOJ/NRAO), T. Izumi et al.

An international research team led by Takuma Izumi, an assistant professor at the National Astronomical Observatory of Japan, has achieved a milestone by observing the nearby active galactic nucleus of the Circinus Galaxy, with an extremely high resolution (approximat...
