ALMA Discovers Earliest Gigantic Black Hole Storm

Overview of the press release

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe.

ALMA image of the distant galaxy J1243+0100 hosting a supermassive black hole in its center. The distribution of the quiet gas in the galaxy is shown in yellow and the distribution of high-speed galactic wind is shown in blue. The wind is located in the center of the galaxy, which indicates the wind is driven by the supermassive black hole.　Credit: ALMA (ESO/NAOJ/NRAO), Izumi et al.
