An international research team has discovered a luminous galaxy hiding behind a quasar, revealing new insights into how galaxies can remain undetected even in well-studied regions of the cosmos.

Not only are they supermassive black holes, but they crate a unique "wagging tail" of super-charged particles.

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

Quasars are the bright centers of young galaxies powered by supermassive black holes. Most quasars are very distant and faint, making them difficult to observe. One quasar, 0957+561, is ...

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe’s gravitational wave background—the constant flow of waves that churn through the cosmos, ...
