This is a list of quasars, with a common name, instead of a designation from a survey, catalogue or list. ... QSO J0313–1806 existing only ~670 million years after ...
[7] [8] The nearest known quasar is about 600 million light-years from Earth, while the record for the most distant known AGN is at a redshift of 10.1, corresponding to a comoving distance of 31.6 billion light-years, or a look-back time of 13.2 billion years. [9] [10] Quasar discovery surveys have shown that quasar activity was more common in ...
That list is available at list of quasars. 3C 295: 1960– z=0.461 This is a radio galaxy. This was the remotest object known at time of discovery of its redshift. This was the last non-quasar to hold the title of most distant object known until 1997. In 1964, quasar 3C 147 became the most distant object in the universe known. [76] [83] [97 ...
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.

Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371; 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib; S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
A large quasar group (LQG) is a collection of quasars (a form of supermassive black hole active galactic nuclei) that form what are thought to constitute the largest astronomical structures in the observable universe. LQGs are thought to be precursors to the sheets, walls and filaments of galaxies found in the relatively nearby universe. [1]
