Very close pairs of quasi-stellar objects.

BURBIDGE G., HOYLE F. and SCHNEIDER P.

Abstract (from CDS):

It is pointed out that there are now known four very close pairs of QSOs with separations <5arcsec and very different redshifts. Several estimates indicates that the probability that they are accidental configurations are small; a conservative estimate of the probability to have four such pairs by random projection yields 3.5x10–3. We conclude either that this is further evidence that QSOs have significant non-cosmological redshift components, or that the pairs must be explained by gravitational lensing.
