Astronomers in their search for gravitational waves as predicted by Einstein have been able to discover 3 closely orbiting supermassive black holes in a galaxy more than 4 billion light years away.
Analyzing 6 systems supposed to contain 2 supermassive black holes, the researchers discovered that one of them contained 3 supermassive black holes - the tightest black hole trio observed at such a large distance.
According to Roger Deane from University of Cape Town in South Africa, "These black holes, which are at the very extreme of Einstein's Theory of General Relativity, are orbiting one another at 300 times the speed of sound on earth."
Deanne added that by utilizing the combined signals from radio telescopes on 4 continents, we are able to detect this exotic system one third of the way across the Universe.
Nothing much is known about these black hole systems that are so close to one another and expel noticeable gravitational waves.
The team utilized a technique Very Long Baseline Interferometry (VLBI) to find out the inner two black holes of the triple system.
VLBI combines the signals from big radio antennae separated by up to 10,000 km to see details 50 times finer than the Hubble Space Telescope.
