large quasar group

(structure consisting of a collection of quasars)

The term large quasar group (LQG) is pretty-much self-descriptive: grouped quasars. They are seen at high redshift (z) as are quasars. They are considered large scale structures and a possible precursor to large scale structures found in the recent (smaller Z) universe.
