A new apparent quasar pair: Q2225-403A,B.

DECARLI R., TREVES A. and FALOMO R.

Abstract (from CDS):

We report the serendipitous discovery of a previously unknown quasar at 10.5 arcsec from Q2225-403 (z = 2.410). The observation of the broad emission line of Mgiiλ2798 and of the surrounding Feii multiplets indicates that the companion quasar is at z = 0.932. The spectrum of Q2225-403 shows a number of absorption lines, the most noteworthy is the Mgii line at the same redshift of the companion, suggesting that we are probing the gas within the halo ∼80 kpc from the closer quasar. From high-resolution near-infrared images, we were able to resolve the host galaxies of the two quasars. Basing on the known surface density of quasars in the 2dF survey, we estimate that the probability of finding such a close pair is ≲1 per cent.
