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

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had ...

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, ...

Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results show that this radiation dampens the wounded galaxy's ...

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 ...

"This shows how effective the approach of 'Discover with Subaru Telescope, explore with James Webb' can be." Using a powerful combination of the Subaru Telescope and the James Webb Space Telescope ...

As two distant galaxies trade blows in an ancient duel billions of years old, one belligerent has clearly proven itself more ruthless than the other. Each time the galaxies conclude their posturing ...
