Astronomers detect most energetic outflow from a distant quasar
The image at left shows an artist’s conception of the central portion of the galaxy that hosts the quasar SDSS J135246.37+423923.5 viewed at optical wavelengths. Thick winds obscure our view, and imprint signatures of the energetic outflow on the SDSS spectrum. The image at right shows the same artist’s view at infrared wavelengths, as seen by the Gemini GNIRS detector. The thick outflow is transparent at infrared wavelengths, giving us a clear line of sight to the quasar. The infrared spectrum yields the quasar redshift, and from that reference frame, we measured the record-breaking outflow velocity.
