Supermassive Black Hole Pairs to Be Found in Colliding Galaxies


Michael Koss and Eureka Scrientific Inc have formed a team, and together they observed many pairs of galaxies, that are in the final stages of merging together into a single, much bigger galaxy. The team looked through the thick walls of dust and gas that were around the cores of the galaxies, and they’ve seen pairs of supermassive black holes – each of them was once at the center of one of the original galaxies. They got drawn closer before they actually became one huge black hole.

Dr. Koss said that it was actually awesome to see the nucleus of the merging galaxies that were associated with black holes. The images are ten times sharper than what a telescope on the ground can get.

The team made the last survey of the cores if the near galaxies in infrared light. They used high-resolution pictures, which were taken by the NASA Hubble Space Telescope and by the W. M. Keck Observatory from Hawaii. The work of the Hubble Space Telescope represents 20 years of snapshots.

481 galaxies were researched in total

The scientists had in mind galaxies that had an average distance of 330 million light-years from Earth. They took into account 96 galaxies from the archive of Keck Observatory, and 385 galaxies from the archive of the Hubble Space Telescope. These galaxies are the result of the work of the astronomers. Most of these galaxies have almost the same size as Milky Way and the Andromeda galaxies.

The survey that happened shoed much information about the hidden black holes, that are either obscured or highly luminous. It’s really the first time they’re discovered. There are more supermassive black holes than they thought, and they grow larger in the final stages of the galaxy mergers.
