Supermassive Black Hole Being Pushed Away By Gravitational Waves From Its Galaxy, Observers Say
The universe is a wonder for scientists, and there is no change with the recent observation. It is found that a monster black hole is pushed from its galaxy by gravitational waves and is reportedly moving at a speed of 4.7 million mph which is enough to pull out it from the Galaxy in 20 million years. It is already spotted 35,000 light-years from the center of its galaxy, and initially, it was placed at the center of it.
The galaxy called 3C 186 is located at eight billion light-years from the solar system, and the movement of the black hole was noted for some time. Recently it is concluded that the movement could be due to none other than gravitational waves. The phenomenon was suggested first time by Albert Einstein almost 100 years back, and last year the scientists of LIGO also confirmed the phenomenon by pointing out the merger of two black holes where gravitational waves created.
"We calculate that the energy to move the black hole out is equivalent to 100 million supernova exploding," said Stefano Bianchi, co-author of the study from Roma Tre University, Italy. The Hubble space images showed the presence of a quasar in the galaxy which is usually indicating a black hole. The reports confirm that many galaxies have a supermassive black hole at the center of them, and the current one is quite far from the center.
The Hubble data reveals that the 3C186 galaxy has tidal tails, an arc-like feature, and this usually appears when there is the presence of gravitational waves, especially from galaxy merger. Researchers believe that the merging could be started by the collision of 2 galaxies almost 1 to 2 billion years back. When the central black holes of both the galaxies countered each other, they started emitting gravitation waves to a single direction. Finally, the merging of black hole took place, and the emission stopped. The created supermassive black hole started moving in the opposite direction, says the researchers.
