The object was first identified by R.A. Preston in 1985.[13] Before then, it was unnoticed. Analysis in 1998 reveal that it might be relatively dusty based on the quasar'sX-ray properties;[14] Long thought to be solitary, theCHiPS (Clusters Hiding in Plain Sight) Survey found PSZ2 G317.79+26.63, a massivegalaxy cluster surrounding the quasar.[4] The team analyzed data from the2MASS,NVSS,ROSAT,SUMSS, andWISE all-sky surveys in order to locate powerful sources ofinfrared,radio, andX-ray light. The goal was to discover new galaxy clusters that were previously misidentified as isolated sources of X-ray light due to the central quasar's brightness.[15][4]
As an individual object, PKS 1353−341 has a centralmass 300 billion times that of theSun,[3] which is 1/4 of the Milky Way's mass. It has anabsolute magnitude of −22.4 in the blue passband,[3] making it very luminous. The galaxy hosting PKS 1353−341 is a largeelliptical galaxy.[4][7] Typical of quasars, PKS 1353−341 has two jets originating from the center of the galaxy. When combined with the surrounding cluster, both have a mass of6.9+3.4 −2.6×1014M☉, making it a thousand times more massive than our own galaxy.[4]
