LBQS 1429-008 (QQ 1429−008, QQ 1432−0106, QQQ J1432−0106) is a distant physical triple quasar located 10.5 billion light years away from Earth in the constellation of Virgo.[2] It was discovered in 1989 by Paul Hewett and his colleagues from the Institute of Astronomy, Cambridge in England.[3]
Originally a binary pair instead of a gravitational lensed quasar,[4] a third quasar component was found in LBQS 1429-008 during an observation by a team of researchers from Keck Observatory who used a 10-meter telescope.[5] This makes them the first physical triple quasar discovered.[6][7] The system has an estimated separation of 30-50 kiloparsecs.[7]
