Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational ...

The first-ever sighting of starlight from a galaxy hosting one of the most distant quasars known has revealed an astronomical oddity. Quasars — blazingly bright galactic cores — owe their brilliance ...

APM 08279-5255 is a massive black hole (quasar) that contains about 140 trillion times the amount in all of Earth’s oceans ...

Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...

CAMBRIDGE, MASS. — For the first time, astronomers have detected starlight from distant galaxies that host extremely bright supermassive black holes called quasars. “Ever since the discovery of ...

University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say “sideline quasars” likely teamed up with it to heat abundant ...

(Nanowerk News) A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique ...
