The James Webb Space Telescope has captured images of two early-universe quasars, shedding light on the relationship between black holes and their host galaxies. This…
Artistic illustration of the thick dust torus thought to surround supermassive black holes and their accretion disks. Durham University researchers using ALMA have discovered that…
Through their study of radiation produced by supermassive black holes in quasars, scientists found that spectral energy distribution is not influenced by a quasar’s intrinsic…
A new study shows that, by dragging space-time, supermassive black holes can rip apart the violent whirlpool of debris (or accretion disks) that encircle them,…
The compact radio jet in the center of the Teacup galaxy blows a lateral turbulent wind in the cold dense gas, as predicted by the…
This artist’s concept shows the brilliant glare of two quasars residing in the cores of two galaxies that are in the chaotic process of merging.…

Schematic representation of a quasar. The hot accretion disk in the center surrounds the black hole, which is invisible here. A dense distribution of gas…
Illustration of simulated Webb images of quasar and galaxy surrounding quasar. Researchers will take images of each target with Webb’s Near-Infrared Camera (NIRCam), like the…
A quasar – the most luminous persistent source of light in the universe. Credit: NASA A discovery that provides new insight into how galaxies evolve.…
This is an artist’s concept of a galaxy with a brilliant quasar at its center. A quasar is a very bright, distant and active supermassive…
Astronomers have discovered two pairs of quasars in the distant Universe, about 10 billion light-years from Earth. In each pair, the two quasars are separated…
Four of the newfound quadruply imaged quasars are shown here: From top left and moving clockwise, the objects are: GraL J1537-3010 or “Wolf’s Paw;” GraL…
This artist’s impression shows how the distant quasar P172+18 and its radio jets may have looked. To date (early 2021), this is the most distant…
An artist’s illustration of the Chandra spacecraft in orbit. Credit: MSFC Quasars are perhaps the best-known kinds of active galactic nuclei (AGN), galaxies whose central…
An artist’s impression of quasar J0313-1806 showing the supermassive black hole and the extremely high velocity wind. The quasar, seen just 670 million years after…
