James Webb Space Telescope sees lonely supermassive black hole-powered quasars in the early universe
"It's difficult to explain how these quasars could have grown so big if they appear to have nothing to feed from."
Ancient supermassive black hole is blowing galaxy-killing wind, James Webb Space Telescope finds
Using the James Webb Space Telescope (JWST), astronomers have spotted the earliest powerful "galaxy-size" wind blowing from a feeding supermassive black hole-powered quasar. The powerful wind is pushing gas and dust from its galaxy at incredible speeds, supressing star birth in its host galaxy.
James Webb Telescope Discovers Quasars Where They Shouldn’t Exist
Astronomers used the James Webb Space Telescope to detect ancient lonely quasars with murky origins. They appear to have few cosmic neighbors, raising questions about how they first emerged more than 13 billion years ago.
James Webb Space Telescope Spots Massive Black Hole With Half the Mass of Its Surrounding Galaxy
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 distant quasar.
Webb telescope reveals rapid growth of primordial black hole
At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. In fact, these objects, which increase in mass over time by eating material that wanders too close,
'Hungriest ever' black hole discovered thanks to James Webb Space Telescope
Scientists have discovered a low-mass supermassive black hole feasting on material at a rate never seen before. A supermassive black hole is the largest type of black hole, with its mass being hundreds of thousands,

Astronomers explore the properties of an obscured hyperluminous 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.
