Dark matter could magnify the jets of a ravenously feeding supermassive black hole

Astronomers have discovered that a jet of plasma erupting from a distant supermassive black hole at near-light-speed is being gravitationally lensed by an unseen clump of dark matter. The discovery could tell us about the source of cosmic "ghost" particles called neutrinos.The supermassive black hole in question is powering a type of quasar called a blazar. All quasars involve supermassive black holes surrounded by vast quantities of material upon which the black holes feed. Material that isn't
