Elusive supermassive black hole ‘couples’ discovered by NASA (VIDEO)

The ‘couples’ form when two galaxies collide and merge with each other, forcing their supermassive black holes close together.

Five black hole ‘couples’ were identified by astronomers using a combination of data from a number of telescopes, including NASA’s Chandra X-ray Observatory, the Wide-Field Infrared Sky Explorer Survey (WISE) and the Sloan Digital Sky Survey (SDSS).

Previously, fewer than 10 confirmed pairs of growing black holes were observed from X-ray studies – and these sightings were based mostly on chance detections.

“Astronomers find single supermassive black holes all over the universe. But even though we’ve predicted they grow rapidly when they are interacting, growing dual supermassive black holes have been difficult to find,”explains Shobita Satyapal, lead author of a research paper on the discovery.

Scientists undertook a systematic search of telescope data to identify the dual black hole systems.

Closely-separated pairs of X-ray sources were found in five systems, providing evidence that they contain two growing supermassive black holes.

The data also suggests that these giant black holes are buried in large amounts of dust and gas.
