Astronomers have spotted a massive black hole which has grown rapidly than his host galaxy, and has a mass of nearly seven billion suns. The discovery was made when scientists were studying the growth of black holes across cosmic time.
The latest discovery contradicts earlier observations that black holes and their host galaxies grow at an identical rate. This black hole was found in the galaxy CID-947, and is one of the most gigantic black hole ever seen. Astronomers have explained about the black hole in the journal Science that was formed about 2 billion years after the Big Bang. Yale professor of Astrophysics and co-researcher C. Megan Urry said that the project specifically targeted moderate black hole that inhabit galaxies today.
“It was quite a shock to see such a ginormous black hole in such a deep field,” said Urry.
The mass of the surrounding galaxy has baffled the research team. Lead author Benny Trakhtenbot, a researcher at the ETH Zurich, Switzerland stated that the measurements correspond to the mass of a typical galaxy. We therefore have a gigantic black hole within a normal-size galaxy, he added. Usually, galaxies have a black hole at the core, which includes the Milky Way. The result was so surprising that outside experts were called in to very the results.
The research team was supported by the W. M. Keck Observatory in Hawaii and Chandra COSMOS legacy survey during the work. The international team included astronomers from the University of Hawaii, Havard university, Max-Planck Institute in Germany, Yale University, Oxford University and INAF-Osservatorio Astronomico di Roma. Black holes were predicted by Albert Einstein in 1916 by the general theory of relativity. American astronomer John Wheeler was the first person to discover a black hole in 1971, and coined the term “black hole.”[ Source ] [ Via ]
