How Supermassive Black Holes Stifle Star Formation In Neighbouring Galaxies

This artist's illustration shows a swirling accretion disk around a brilliant quasar. Quasars, which are extremely luminous supermassive black holes, warm up the gas in their galaxy, which suppresses star formation. But new research says that luminous quasars can even suppress star formation in neighbouring galaxies. Image Credit: NASA, ESA, Joseph Olmsted (STScI)

We know that supermassive black holes can inhibit star formation in their galaxies. But new research and JWST observations show that the most luminous quasars can actually suppress star formation in neighbouring galaxies. SMBH may have played a more pronounced role in shaping the early Universe than previously thought.
