List of quasars

List of quasars

This is a list of quasars.

Proper naming of quasars are by Catalogue Entry, Qxxxx±yy using B1950 coordinates, or QSO Jxxxx±yyyy using J2000 coordinates. They may also use the prefix QSR.

List of quasars

List of visual quasar associations

This is a list of double quasars, triple quasars, and the like, where quasars are close together in line-of-sight, but not physically related.

It should be noted that quasars that have a recessional velocity greater than the speed of light (c) are very common. Any quasar with z>1 is going away from us in excess of "c". Early attempts to explain superlumic quasars resulted in convoluted explanations with a limit of z=2.326, or in the extreme z<2.4. z=1 means a redshift indicating travel away from us at the speed of light. The majority of quasars lie between z=2 and z=5 .

Most Distant Quasars

The first time that quasars became the most distant object in the universe was in 1964. Quasars would remain the most distant objects in the universe until 1997, when a pair of non-quasar galaxies would take the title.
