Chandra Shows Giant Black Hole Spins Slower Than Its Peers

H1821+643 is a quasar powered by a supermassive black hole, located about 3.4 billion light years from Earth. Astronomers used NASA’s Chandra X-ray Observatory to determine the spin of the black hole in H1821+643, making it the most massive one to have an accurate measurement of this fundamental property, as described in our press release. Astronomers…
