... through gravitational and frictional forces to millions of degrees while radiating enormous amounts of energy as it is swallowed up out of sight. Quasars and AGN are also synonymous with powerful jets, which can blast outwards at opposite ends from...
... strong gravitational pull, subsequently emitting lots of light and producing a brilliant beacon called a quasar. “The type of disc we see is a scaled-down quasar that we did not expect to exist,” Bianchi explained. “It’s the same type of disc we see...
... measurement by the H0LiCOW collaboration using gravitationally-lensed quasars, contradicts that made using other methods and the... measured the Hubble constant by measuring light from distant quasars that is bent by massive galaxies stationed in the ...
... discovery in the Markarian 231 galaxy, located 600 million light years away from Earth, suggests that a quasar in it is actually the product of two black holes, of vast difference in size, that perform a peculiar gravitational twirl around...
... of Earth! One important result of the joint Arecibo-RadioAstron work was the observation that the temperature of quasar 3C 273 is so high that it forces astronomers to reconsider the synchrotron emission mechanism invoked decades ago to account for...
...cycle, galaxies big and small, serene star clusters and blazing quasars, and more are all included in the list. 2) Superlatives:...with unusually high or low metal content, the most distant quasar and fastest-spinning pulsar, and the densest galaxy. 3) ...
