Astronomers Just Found a Monster Black Hole Formed By 3 Colliding Spiral Galaxies Video

Astronomers have spotted a super-massive black hole, 3 billion times extra massive than our Sun. This particular super massive black hole is situated in a distant galaxy some 1.8 billion light-years away from Earth. The galaxy, this black is situated in, is called IRAS 20100–4156, and it's formed from a trio of spiral galaxies that are at present in the middle of colliding into one another. The judgment of the supermassive black hole at the hub of this collision was actually came by accident, while performing a test observation of the CSIRO's latest telescope – the Australian Square Kilometre Array Pathfinder (ASKAP).
Astrophysicist Lisa Harvey-Smith was treatment the telescope to normally measure the maser discharges pending from IRAS 20100–4156. She told Anna Salleh at the ABC "[I] thought it would be quite a mundane thing," But after investigative the readings in combination with measurements from another CSIRO telescope – the Australia Telescope Compact Array – Harvey-Smith exposed that the gas inside the maser was travelling at very quick speeds.
 Travelling nearly 600 kilometres per next about the centre of IRAS 20100–4156 – which was twice as fast as researchers would have anticipated – the speed of the gas hinted at a supermassive black hole developing right at the hub of the galaxy.
Harvey-Smith told the ABC "The black hole at the centre of our galaxy is only 4 million solar masses, so this one is a friend in comparison. This very fast motion of the gas tells us about how massive the black hole is. The really exciting thing about this is it is a straight measurement of the mass of the black hole by stuff that's swirling approximately it."
According to the present theories, when galaxies collide like this and develop a supermassive black hole, it ultimately results in what's called a starburst, where stars form at an unusually high rate.
According to Harvey-Smith, this detection of monster black holes and knowing its mass helps provide us a better insight of how galaxies form throughout the Universe.
She told the ABC "We want to know whether galaxy collisions, and the formation of supermassive black holes, have actually driven the star formation rates that we see in galaxies and how that's changed throughout time,"
The study paper has been accepted for proper issuance in the Monthly notice of the Royal Astronomical Society.
