Discovery of a Probable Physical Triple Quasar

Abstract

We report the discovery of the first known probable case of a physical triple quasar. A previously known double system, QQ 1429 008 at , is shown to contain a third, fainter QSO component at the same z p 2.076 redshift. Deep optical and IR imaging has failed to reveal a plausible lensing galaxy group or a cluster, and we are unable to construct any viable… (More)
