Discovery of a New Quasar: SDSS J022155.26-064916.6
Abstract
We report the discovery of a new quasar: SDSS J022155.26-064916.6. The object was selected as a white dwarf candidate for a sample of spectrophotometric standards for the Dark Energy Survey. It was imaged by SDSS and classified as a star with a cosmic ray hit, but the quasar was not selected as a spectroscopic target for SDSS-III. WISE data place the object in the QSO/Seyfert range; however, no spectroscopic confirmation of the object as a quasar previously existed. In the investigation of this object as a potential white dwarf, the object was identified by its spectrum to be a quasar. The spectrum is presented with MgII, OII, Hb, and OIII identified, and the average redshift is determined to be z ≈ 0.799 ± 0.0086. The luminosity distance is DL = 5074.7 Mpc. The Spectral Energy Distribution and a comparison with objects from the SDSS DR7 quasar catalog are also presented.
