Gemini Speckle Imaging of Dual Quasar Candidates.

HOWELL S.B., SHEN Y., FURLAN E., GNILKA C.L. and STEPHENS A.W.

Abstract (from CDS):

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.
