Scientists at the Univeristy of Cambridge discover giant black holes
A team of researchers, led by a scientist of Indian origin at Cambridge University have found a cluster of giant, rapidly-growing black holes from an early period in the cosmic history.
According to the scientists, the black holes remained undetected till now because they were wrapped under thick clouds of obscuring dust. But, they were emitting huge amounts of radiation through violent interactions with their parent galaxies and are now they're detected using the latest, cutting edge infrared surveys being carried out on the UK Infrared Telescope (UKIRT).
A black hole is a compact object with such a strong gravitational force, that nothing can escape it's gravitational field, including light.
According to the study, the most extreme object is a supermassive black hole called ULASJ1234+0907 that is 11 billion light years away from the earth. It's weighs more than 10 billion times than the mass of our sun and it's 10,000 times greater than the supermassive black hole in our own Milky Way. Thus, it is one of the the most massive black holes ever detected.
The scientists believe that there might be as many as 400 such black holes in our universe.
Manda Banerji, of Cambridge University is the lead author of the paper. In a statement, she said said, “These results could have a significant impact on studies of super-massive black holes, Most black holes of this kind are seen through the matter they drag in. As the neighboring material spirals in towards the black holes, it heats up. Astronomers are able to see this radiation and observe these systems. Although these black holes have been studied for some time, the new results indicate that some of the most massive ones may have so far been hidden from our view.”
The team of scientists believe that the new discovery will help to find out more details about the physical processes that governs the growth of all supermassive black holes.
