Six galaxies have been revealed to be trapped in a supermassive black hole that formed less than one billion years after the Big Bang, shedding light on how some of the largest structures in the universe are brought into being.
The black hole, and the disc of matter around it is collectively known as quasar SDSS J103027.09+052455.0.
Marco Mignoli, an astronomer at the National Institute for Astrophysics (INAF) in Bologna who led the research, compared the way in which the black hole managed to ensnare these six galaxies to a spider’s web, made up of “cosmic filaments” of gas and dark matter.
The cosmic web filaments are like spider’s web threads … The galaxies stand and grow where the filaments cross, and streams of gas – available to fuel both the galaxies and the central supermassive black hole – can flow along the filaments.
The earliest black holes in the Universe are thought to have formed from the collapse of the first stars, but doubt remains over how they eventually grew to such truly incomprehensibly large sizes.
The researchers postulate that the filament “web” may have formed with the assistance of enigmatic dark matter, which is theorized to have drawn large volumes of gas together during the earliest ages of the universe.
This particular “web” is over 300 times the size of the Milky Way, and there are likely many more out there waiting to be explored, say the researchers.
“We believe we have just seen the tip of the iceberg, and that the few galaxies discovered so far around this supermassive black hole are only the brightest ones,” said co-author Barbara Balmaverde, an astronomer at INAF in Torino, Italy.
The discovery marks the first time such a close grouping has been seen so soon after the Big Bang and will help to improve humanity’s understanding of supermassive black holes like the one at the center of our own galaxy.
