A large quasar group (LQG) is a collection of quasars that form what are thought to constitute the largest astronomical structures in the known universe. Prominent LQGs · List of LQGs · See also · References. A quasar (/ˈkweɪzɑːr/) (also quasi-stellar object or QSO) is an active galactic nucleus of very .. The largest known is estimated to consume matter equivalent to Earths per minute. Quasar luminosities can vary considerably over time. What's the biggest thing in the universe? That would be a cluster of quasars so large it would take a vehicle traveling at the speed of.
Our team has been looking at similar cases which add further weight to this challenge and we will be continuing to investigate these fascinating phenomena. Quasars can be detected over the entire observable electromagnetic spectrum including radio , infrared , visible light , ultraviolet , X-ray and even gamma rays. Naval Observatory Astronomical Applications. CFHQS J CFHQS J This is significant not just because of its size but also because it challenges the Cosmological Principle, which has been widely accepted since Einstein. LQGs are thought to be precursors to the sheets, walls and filaments of galaxies found in the relatively nearby universe.

The coloured background indicates the peaks and troughs in the occurrence of quasars at the distance of the LQG. Quasars would remain the most distant objects in the universe until , when a pair of non-quasar galaxies would take the title. Retrieved 19 June Navigation menu Personal tools Not logged in Talk Contributions Create account Log in. One idea is that jets, radiation and winds created by the quasars, shut down the formation of new stars in the host galaxy, a process called 'feedback'. This particular group is so large that it challenges modern cosmological theory, researchers said. Its redshift was so much greater than the previous record that it was believed to be erroneous, or spurious. In comparison, the black hole at the center of the Milky Way is thought to have a mass only 4 million to 5 million times that of the sun.
