A team of researchers from the University of Cambridge, led by Dr Manda Banerji, has discovered previously undetected supermassive black holes in the deepest regions of the early universe. The study is published in the Monthly Notices of the Royal Astronomical Society.
A Royal Astronomical Society press release said the team used “cutting-edge infrared surveys of the sky to discover a new population of enormous, rapidly growing supermassive black holes in the early Universe”. Apparently, these black holes have been hidden from our site due to a thick layer of dust that surrounds them. One of the super massive black holes, labeled ULASJ1234+0907, is 10,000 times the size of our own Milky Way galaxy. It, and other black holes like it, is emitting enormous radiation through violent interactions with its host galaxy.
Dr Manda Banerji said, “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.” He went on to say, “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.”
Most of the massive black holes are located at the center of galaxies. Due to collisions with other galaxies, they are often surrounded by massive clouds of dust. The team from Cambridge used infrared surveys being carried out on the UK Infrared Telescope (UKIRT) to look past the dust and locate the giant black holes for the first time. This research could have significant impact on the way black holes are studied in the future. For more information, visit http://www.ras.org.uk.
