1343+264: A close quasar pair.
01 January 1988
Two quasars of virtually identical redshift separated by 9. 5" have been discovered on a CFHT grens plate. Subsequent spectroscopy reveals substantial differences in their spectral line strengths which appear to be incompatible with a gravitational lens hypothesis. Furthermore, deep CCD images of the field do not show any indication of a lensing galaxy or extended Ly alpha emission. It is likely that these quasars are a physically related pair, possibly residing in a cluster of galaxies at z=2.03.
