1343. 4+2640 - a close quasar pair
Journal Article

· Astrophys. J.; (United States)
Two quasars of virtually identical redshift separated by 9.5 arcsec 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. 13 references.
