November 30, 2012 - Astronomers
have found a galaxy whose super-luminous nucleus--called a quasar--is burning 100 times as much energy as the entire Milky Way
Though theory has long predicted that quasars this powerful should exist, the newly-discovered object, known as SDSS J1106+1939, is by far the most energetic ever observed. The quasar
is powered by a supermassive black hole that lies at its center.
Scientists made the discovery using the X-shooter spectrograph instrument attached to ESO's Very Large Telescope. The spectrograph split light coming from the quasar into its component wavelengths, allowing astronomers to observe the movement of material close to the quasar. The team calculated that the quasar is spewing an annual 400 suns worth of gas and dust, at a velocity of nearly 5000 miles per second.

A quasar with the largest ever outflow has been found using the European Southern Observatory's (ESO) Very Large Telescope (VLT).
The object is at least five times more powerful than previously observed quasars, with energies expected from theoretical...

(Phys.org) - Astronomers using ESO's Very Large Telescope (VLT) have discovered a quasar with the most energetic outflow ever seen, at least five times more powerful than any that have been observed to date. Quasars are extremely bright galactic centres powered by supermassive black holes. Many blast huge amounts of material out into their host...
