In the vast expanse of our universe, astronomers have stumbled upon a perplexing phenomenon that challenges our understanding ...

Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei ...

The black hole’s mass is over half that of all the stars in the surrounding galaxy, a record for any galaxy hosting a quasar.

Discovered in late 2022, COS-87259 is a hyperluminous quasar at a redshift of 6.85. The AGN is heavily obscured and has a bolometric luminosity of approximately 50 trillion solar luminosities.

Black hole in ULAS J1120+0641 has record mass compared to its galaxy. Quasar's black hole is 1.4 billion solar masses, half its galaxy's mass. Astronomers used JWST to uncover details about this ...

"It's difficult to explain how these quasars could have grown so big if they appear to have nothing to feed from." ...

A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount ...

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists ...

Astronomers used the James Webb Space Telescope to detect ancient lonely quasars with murky origins. They appear to have few ...
