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.
