However, the “lonely” quasars identified by JWST contradict this, suggesting that some supermassive black holes may have formed in isolation, with little nearby matter to sustain them.

“You would expect more [star-forming galaxies] near the quasar than far away, and we found the exact opposite. There’s a big hole around the quasar.” The nearest star-making galaxy is at ...

Quasars are near the extreme high end of this spectrum, but there are other types of AGN that are not quasars. Consider that quasars are so bright because they are almost facing head-on to us.

The newly discovered double quasar, J121503.42–014858.7 and J121503.55–014859.3 — referred to as C1 and C2 by their discoverers — was spotted using the Subaru Telescope on Hawaii's Mauna ...

The team has probed gas outflows in I Zwicky 1, a close-by quasar, to map its system of clouds being blown away at tens to thousands of kilometers per second. Their findings are published in the ...

One of the most mysterious objects in the universe just got a little less mysterious. For sixty years since they were first detected, astronomers have puzzled over what quasars were. What we knew ...

Two spiral galaxies collide, triggering a burst of star formation (red). (Image credit: NASA) When comparing 48 nearby galaxies hosting quasars to 100 non-quasar galaxies, the researchers ...

Astronomers have spied a monster radio jet in the distant universe that’s twice the width of the Milky Way galaxy.The ancient object formed when the universe was less than 10% of its current age ...

In a strange reversal, astronomers have detected a massive black hole but can find no traces of the surrounding galaxy that should be feeding it.

And until now, astronomers couldn't see foreground galaxies outshined by the dazzling quasars behind them. IE 11 is not supported. For an optimal experience visit our site on another browser.
