Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a galactic-scale supermassive black hole-driven wind in HSC J124353.93+010038.5 (J1243+0100 for short), a low-luminosity quasar seen as it was 13.1 billion years ago.

“A supermassive black hole swallows a large amount of matter,” said Dr. Takuma Izumi from the National Astronomical Observatory of Japan (NAOJ) and colleagues.

“As that matter begins to move at high speed due to the black hole’s gravity it emits intense energy, which can push the surrounding matter outward. This is how the galactic wind is created.”

This animation illustrates how black-hole feedback works in quasars.

Dense gas and dust in the center simultaneously fuels the black hole and shrouds it from view.

The black-hole wind propels large-scale outflows of cold gas and powers a shock wave that clears gas and dust from the central galaxy.
