Video Title:
A Quick Look at GSN 069
Description:
Astronomers found X-ray bursts repeating about every nine hours coming from the supermassive black hole at the center of the galaxy GSN 069. By combining data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton, researchers watched this black hole for a span of almost two months. Over that time, they saw the X-ray output from the black hole rise and fall in a repeating pattern. This is evidence that the black hole is consuming a large amount of material — 4 times that of the Moon — about every 9 hours. Regular "eating" has been seen in stellar-mass black holes, but never in their much larger supermassive black hole cousins. This system gives astronomers a chance to study how hot gas flows around a giant black hole and is ultimately consumed.
