Peering Through Dust to Reveal Giant Supermassive Black Holes | Scientists at the University of Cambridge have used cutting-edge infrared surveys of the sky to discover a new population of enormous, rapidly growing supermassive black holes in the early Universe. The black holes were previously undetected because they sit cocooned within thick layers of dust. The new study has shown however that they are emitting vast amounts of radiation through violent interactions with their host galaxies. The team publish their results in the journal Monthly Notices of the Royal Astronomical Society. The most extreme object in the study is a supermassive black hole called ULASJ1234+0907. This object, located in the direction of the constellation of Virgo, is so far away that the light from it has taken 11 billion light years to reach us, so we see it as it appeared in the early universe. The monster black hole has more than 10 billion times the mass of the Sun and 10,000 times the mass of the supermassive black hole in our own Milky Way, making it one of the most massive black holes ever seen. The research indicates that that there may be as many as 400 such giant black holes in the part of the universe that we can observe. “These results could have a significant impact on studies of supermassive black holes” said Dr Manda Banerji, lead author of the paper. “Most black holes of this kind are seen through the matter they drag in. As the neighbouring material spirals in towards the black holes, it heats up. Astronomers are able to see this radiation and observe these systems.” continue reading

Otkrivena gigantska crna rupa Znanstvenici su otkrili crnu rupu koja ima 12 milijardi puta veću masu od Sunca i koja je nastala 900 milijuna godina poslije Velikog praska Supermasivna crna rupa nevjerojatno velike mase, 12 milijardi puta veće od mase našeg Sunca koju su znanstvenici nedavno otkrili ima još jednu zagonetku - vrijeme nastanka. Naime, procijenjeno je da je nastala samo 900 milijuna godina nakon Velikog praska. Golema crna rupa udaljena je 12,8 milijardi svjetlosnih godina od Zemlje. Astronomi nisu u stanju objasniti kako je toliko velika crna rupa mogla nastati tako rano u povijesti svemira, odmah nakon što su nastale prve zvijezde i galaksije.
