large quasar group

(LQG)
(structure consisting of a collection of quasars)

The term large quasar group (LQG) is pretty-much self-descriptive: an astronomical object consisting of a bunch of quasars (five to seventy or more) seen at high redshift (z) (as are quasars in general), grouped in the sky but covering a large expanse, hundreds of megaparsecs across. They are considered large scale structures and a possible precursor to large scale structures found in the recent (smaller z) universe.
