NASA’s Hubble telescope has discovered a critical “missing link” to study the origins of supermassive black holes. Here’s what we know now.
NASA’s Hubble Telescope found the ‘missing link’ between young star-forming galaxies and the first supermassive black holes! Astronomers believe that the identified rapidly growing black hole in the early universe by the Hubble telescope will solve the mystery about the beginning of the universe. NASA scientists say that it’s the first time when we have actually spotted one of the rare objects that bridges the gap between the understanding of the young star-forming galaxies and the first supermassive black holes. What makes history? The discovery of the monster black hole, dubbed GNz7q, which had been lurking unnoticed in one of the best-studied areas of the night sky.
The scientists used Hubble data from the Advanced Camera for Surveys to figure out that GNz7q existed only 750 million years after the big bang. GNz7q is a newly generated black hole, according to the scientists. Hubble discovered a compact source of UV and infrared light. This could not be due to galaxies emitting light, but it is compatible with the radiation that would be expected from objects falling into a black hole. Theories and computer simulations anticipated rapidly expanding black holes in dusty, early star-forming galaxies, but they had never been detected until today.
What this discovery means
After discovering a compact source of ultraviolet (UV) and infrared radiation, Hubble confirmed that GNz7q is a recently formed black hole. Scientists have only ever predicted the existence of these missing connections in dusty, early star-forming galaxies, but have never seen any.
“Our analysis suggests that GNz7q is the first example of a rapidly growing black hole in the dusty core of a starburst galaxy at an epoch close to the earliest supermassive black hole known in the universe,” an astronomer at the Niels Bohr Institute of the University of Copenhagen explained about the discovery.
According to NASA, the discovery of GNz7q could be a missing connection between young star-forming galaxies and the first supermassive black holes. NASA explained that the dusty starburst galaxy and the quasar are both present in GNz7q, with the quasar light exhibiting the dust reddish colour. Also, GNz7q lacks a number of characteristics seen in normal, bright quasars, which is most likely due to the fact that the core black hole in GN7q is still in its early phase. Having said that. these characteristics are identical to those of a young, transition phase quasar anticipated in simulations but never observed in the universe. Now, the research team hopes to systematically search for similar objects.
