Astronomers have just discovered an unknown structure in a galaxy that had been hidden in the “shadows.” They accomplished this by extending the dynamic range…
Dr. HE Zhicheng and his coworkers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences created a new…
Testing a new, direct method for determining the masses of supermassive black holes. Astronomers of the Max Planck Institute for Astronomy have, for the first…
Researchers will examine three active supermassive black holes – known as quasars – their host galaxies, and their neighborhoods to better detail these distant objects…
A discovery that provides new insight into how galaxies evolve. At the center of galaxies, like our own Milky Way, lie massive black holes surrounded…
Looking back in time, Webb will see quasars as they appeared billions of years ago Outshining all the stars in their host galaxies combined, quasars…
Gemini North spectroscopically resolves a pair of quasars that are closer together than any yet discovered in the distant Universe. Astronomers have found two close…
Machine-Learning Methods Lead to Discovery of Rare “Quadruply Imaged Quasars” That Can Help Solve Cosmological Puzzles With the help of machine-learning techniques, a team of…
Seeing Dual Quasars Is Like Finding a Needle in a Haystack Inhabitants of our Milky Way galaxy living several billion years from now will have…
Astronomers have discovered evidence for an extraordinarily long jet of particles from a supermassive black hole in the early Universe, using NASA’s Chandra X-ray Observatory….
Astronomers may have discovered the most distant jet emitting X-rays. The source of this jet is a rapidly growing supermassive black hole, or quasar, located…
With the help of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered and studied in detail the most distant source of…
Scientists of the P. N. Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), the Moscow Institute of Physics and Technology (MIPT) and…
Nearly every galaxy hosts a monster at its center — a supermassive black hole millions to billions times the size of the Sun. While there’s…
Quasars are perhaps the best-known kinds of active galactic nuclei (AGN), galaxies whose central supermassive black holes are luminous, sometimes brighter than the rest of…
The most distant quasar known has been discovered. The quasar, observed just 670 million years after the Big Bang, is 1000 times more luminous than…
Fully formed just 670 million years after the Big Bang and powered by the earliest known supermassive black hole, the quasar provides insight into the…
