- Astronomers including one of the 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.
- This could help astronomers better understand how giant black holes grow and how they may produce the strongest gravitational wave signals 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 discovered by combining data from a suite of different observatories including
- NASA's Chandra X-ray Observatory,
- The Wide-Field Infrared Sky Explorer Survey (WISE)
- The ground-based Large Binocular Telescope in Arizona.
