In a groundbreaking study published on arXiv, astronomers from Seoul National University, South Korea, and collaborators across the globe have uncovered 62 new luminous quasars as part of the All-sky ...

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, ...

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 ...

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 ...

Using the wide-field survey capabilities of the Subaru Telescope, astronomers discovered active supermassive black holes, or quasars, in the distant universe and then studied them with the James Webb ...

A pair of quasars that existed when the universe was only 3 billion years old has been spotted by the Hubble Space Telescope.

"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 ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...
