The close QSO pair Q1548+114A, B

IPCS spectroscopic and CCD imaging observations have been made of the QSOs Q1548+114A and B, which are separated by 4.8 arcsec and have redshifts of 0.44 and 1.90. There is no evidence either for line-locking in the absorption spectrum of B or for associated absorption in B at the redshift of A, bot...

Description
Summary:IPCS spectroscopic and CCD imaging observations have been made of the QSOs Q1548+114A and B, which are separated by 4.8 arcsec and have redshifts of 0.44 and 1.90. There is no evidence either for line-locking in the absorption spectrum of B or for associated absorption in B at the redshift of A, both of which had previously been reported. Galactic H and K absorption is present in both spectra. This remains the closest pair of distinct QSOs, although the number of QSOs has increased tenfold since its discovery, and its existence is consistent with a random distribution of QSOs on the sky.
