Astronomers measure dark matter ‘haloes’ around hundreds of ancient black holes for 1st time

A staff of astronomers has, for the primary time, “weighed” darkish matter haloes surrounding actively feeding supermassive black holes within the vibrant hearts of historic galaxies.

These black hole-powered hearts, or quasars, are sometimes brighter than the mixed gentle of each star within the galaxies round them. These tremendous luminous central areas are “fired up” when supermassive black holes, which might have lots billions of occasions that of the solar, begin greedily feeding on surrounding matter.
