The galactic cores, containing huge black holes, could help explain how the universe developed into the complex cosmos it is today.
A team of astronomers has spotted the most distant merging galactic cores yet, seen as they were when the universe was less than a billion years old. The duo of active galactic centers, called quasars, is the only confirmed pair seen during the Cosmic Dawn. The two very red galaxies were spotted by a team using the Subaru telescope’s Hyper Suprime-Cam at a redshift of z=6.05 .
” The Cosmic Dawn is the period of time in the early universe when the first light sources formed. The period lasted from about 50 million years after the Big Bang to when the universe was one billion years old . Seeing quasars so early in the universe was long anticipated, so their direct observation is a welcome one. At the heart of these quasars are black holes—regions of spacetime with gravitational fields so intense that light cannot escape them.
