Supermassive Black Holes Can Starve Their Host Galaxies of Star-Forming Gas, Research Confirms

Astrononomers using the NASA/ESA/CSA James Webb Space Telescope have detected that GS-10578, a massive, quiescent galaxy at redshift of 3.064 (look-back time 11.7 billion years), is expelling large amounts of gas at speeds of about 1,000 km per second, which is fast enough to escape the galaxy’s gravitational pull; these fast-moving winds are being ‘pushed’ out of the galaxy by the central supermassive black hole.

GS-10578 represents a unique opportunity to study how the most massive galaxies in the Universe became -- and stayed -- quiescent. Image credit: Francesco D’Eugenio.
