Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars ...

An international team of astronomers have employed the Spektr-RG spacecraft and various ground-based telescopes to ...

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 ...

Stephanie LaMassa did a double take. She was staring at two images on her computer screen, both of the same object — except they looked nothing alike. The first image, captured in 2000 with the Sloan ...

Astronomers have crafted a map of the most powerful form of supermassive black holes across several billion light years of space. The three-dimensional map plots the locations of 1.3 million quasars, ...

Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the ...

When it comes to quasars and the light they emit, we can say New Mexico State University Professor Christopher W. Churchill ...

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 ...

Giant quasar and little red dots. A NASA/ESA/CSA James Webb Space Telescope (JWST) NIRCam picture of the luminous quasar J1148+5251, an extremely rare active supermassive black hole of 10 billion ...

"Targeted searches will be up to seven times more likely to find gravitational waves from a supermassive black hole binary in a quasar than in a random massive galaxy." When you purchase through links ...
