Another Quadruply Lensed Quasar from the VST-ATLAS Survey

Understand

We report the quadruple nature of the source WISE 025942.9-163543 as observed in the VST-ATLAS survey.

• Spectra of the two brightest images show quasar emission lines at z=2.16.
• The system was discovered by splitting ATLAS "cutouts" of WISE sources with W1-W2 > 0.7, when possible, into three components.
• Followup Magellan images were used to obtain astrometry and g and i photometry, with i=18.78 and 19.73, respectively, for the brightest and faintest components.
