Astronomers find a rare pair of double quasars in the early Universe
... on the discovery team. “This method unambiguously rejected interlopers due to chance superpositions such as from unassociated star-quasar systems.” While the team believe that this very uncommon discovery is robust, there is a small possibility that...

New study doubles the number of known quasars
... as gravity condensed matter further, the first sources of illumination were eventually formed, which might have included quasars. However gaps in our knowledge of this early era still remain and thanks to discoveries such as this, a greater...

Massive quasars can be powered by direct collapse black holes say scientists
... holes, which need DCBHs, which need massive stars to form, but massive stars destroy the chance of quasars evolving by starving it of material. Now, a new computer simulation created by scientists at the Theoretical Design Division at Los Alamos...
