Astronomers spot elusive giant black hole couples
Washington, Oct 4: Astronomers including one of Indian-origin have identified five pairs of supermassive black holes, each containing millions of times the mass of the Sun, in the centres of galaxies.
The findings could help astronomers better understand how giant black holes grow and how they may produce the strongest gravitatiol wave sigls in the universe.
These black hole couples formed when two galaxies collided and merged with each other, forcing their supermassive black holes to comes closer to each other.
The black hole pairs were uncovered by combining data from a suite of different observatories including SA’s Chandra X-ray Observatory, the Wide-Field Infrared Sky Explorer Survey (WISE), and the ground-based Large Binocular Telescope in Arizo. (IANS)
