There Are (super)Giants in the Sky: Searching for Misidentified Massive
  Stars in Algorithmically-Selected Quasar Catalogs
  Thanks to incredible advances in instrumentation, surveys like the Sloan
Digital Sky Survey have been able to find and catalog billions of objects,
ranging from local M dwarfs to distant quasars. Machine learning algorithms
have greatly aided in the effort to classify these objects; however, there are
regimes where these algorithms fail, where interesting oddities may be found.
We present here an X-ray bright quasar misidentified as a red supergiant/X-ray
binary, and a subsequent search of the SDSS quasar catalog for X-ray bright
stars misidentified as quasars.
