Scientist discover unique supermassive black hole with six surrounding galaxies
Astronomers have found at least six galaxies around a supermassive black hole in a form of a “spider’s web” of gas extending to more than 300 times Milky Way

Astromers have found at least six galaxies around a supermassive black hole in a form of a “spider’s web” of gas extending to more than 300 times Milky Way. Calling it a “gigantic cosmic structure”, a research paper published by National Institute for Astrophysics (INAF), Bologna, galaxies were alrey present when universe was less than a billion years old.
Discovered by a team of astromers at National Insitute of Astrophysics with observations me on ESO's Very large telescope (Vlt) and Large bicular telescope (Lbt), it is ‘first’ time that such a structure has been observed in remote era of cosmos. This discovery will furr help scientists understand formation of supermassive black holes along with extraordinary speed with which se objects increase in mass.

Explains 'birth and growth' of Black Holes
Marco Migli from INAF has said that to date, experts do t have a complete explanation of “birth and growth” of black holes. He also said that large quantities of gas flow inside galaxies are t only feeding galaxies but ‘probably’ also supermassive black hole.
"We can think of gas clusters present in this structure as thres of a giant spider's web", explains Migli. “Galaxies are found and evolve where se filaments cross. Large quantities of gas flow inside m, feeding both galaxies mselves and probably supermassive black hole at centre of this structure.”

light from this large web-like “black hole- dominated structure with an estimated mass of one billion times that of Sun”, has travelled to Earth from a time when universe was only 900 million years old. Roberto Gilli, also an astromer at INAF, Bologna and co-author of study published in Astromy and Astrophysics journal, has explained that ir work is an “important piece” to a still incomplete puzzle that describes formation and evolving of extreme celestial objects.
As per study, newly discovered six galaxies can be explained by saying that large amounts of gas y contain, provide fuel that central black hole requires in order to rapidly become supermassive.

'Our discovery supports idea that more distant and massive black holes form and grow within massive dark matter halos within large-scale structures, and that lack of previous sightings of such structures was likely due to observational limits,” says Roberto Decarli.
