A Dense Group of Quasars Form the “Cosmic Himalayas”

Quasars provide some of the most spectacular light shows in the universe. However, they are typically exceedingly rare since they are caused by massive astrophysical forces that don’t happen very often. So it came as quite a surprise when scientists found a group of 11 of them hanging on in the same general area, in what appeared to be equivalent to the galactic countryside. A new paper from Yongming Liang and their co-authors at the University of Tokyo describes this finding, which they dubbed the Cosmic Himalayas, and some of the weird astronomical circumstances that place the discovery in context.
