An article published in the journal “Astronomy & Astrophysics Letters” reports a study on a group of six galaxies surrounding a supermassive black hole which date back to an early epoch when the universe was less than a billion years old. A team of researchers led by Marco Mignoli of the Italian National Institute of Astrophysics (INAF), Bologna, used ESO’s Very Large Telescope (VLT) and the Large Binocular Telescope (LBT) to observe that structure which turned out to be complex as it includes filaments of matter that extend for a distance over 300 times the size of the Milky Way. The gas that concentrates in that structure forms what have been likened to the threads of a spider’s web, and that gas could be responsible for the development of a supermassive black hole in such a remote time.
