Gemini Speckle Imaging of Dual Quasar Candidates

Gemini Speckle Imaging of Dual Quasar Candidates

We observed the candidate dual quasar J2122−0026 with speckle interferometric imaging at the Gemini-North Observatory. Results of our one-hour high resolution ‘Alopeke imaging observation agree with and confirm Hubble Space Telescope imaging of the pair separated at ∼0.″5. These observations show th...

description We observed the candidate dual quasar J2122−0026 with speckle interferometric imaging at the Gemini-North Observatory. Results of our one-hour high resolution ‘Alopeke imaging observation agree with and confirm Hubble Space Telescope imaging of the pair separated at ∼0.″5. These observations show that sub-arcsec dual quasar candidates as faint as r  ∼ 19 can be observed and detected using speckle imaging at Gemini. “Do not go where the path may lead, go instead where there is no path and leave a trail.” Ralph Waldo Emerson
