The mass of gas being expelled from 'Pablo's Galaxy' is greater than the amount needed for star formation, effectively starving the galaxy.
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black hole s can starve their host galaxies of the fuel they need to form new stars.Astronomers, using the NASA/ESA James Webb Space Telescope , have confirmed that supermassive black hole s can deprive their host galaxies of the gas required for star formation.
“Based on earlier observations, we knew this galaxy was in a quenched state: it’s not forming many stars given its size, and we expect there is a link between the black hole and the end of star formation,” said co-lead author Dr Francesco D’Eugenio from Cambridge’s Kavli Institute for Cosmology. “In the early universe, most galaxies are forming lots of stars, so it’s interesting to see such a massive dead galaxy at this period in time,” explained co-author Professor Roberto Maiolino from the Kavli Institute for Cosmology. He noted that since the galaxy reached this massive size, the process that halted star formation likely occurred quite rapidly.
While similar galaxies with active black holes also have outflows of hot gas, the expelled gas in Pablo’s Galaxy is unique. Webb detected a new component: colder, denser gas that emits no light, making it invisible to previous
