Cool Gas Circles Milky Way’s Supermassive Black Hole

"'This is the first indication of accretion with a direction of rotation,' says Lena Murchikova, a theoretical astrophysicist at the Institute for Advanced Study in Princeton, N.J., and lead author of a study reporting the new results, published June 5 in the journal Nature. Murchikova and her colleagues used data gathered in 2015 by the Atacama Large Millimeter/submillimeter Array (ALMA) to discover the thin accretion disk of material extremely close to the black hole that is sending streams of material spiraling inward. Earlier studies had revealed a more distant disk of warm gas farther away from the black hole which may feed the newfound cooler disk."
