Scientific paper

Images with about 1-arcsec resolution are presented of four high-redshift QSOs (0952 + 179, 1011 + 250, 1100 - 264, and 1209 + 107) which have reported absorption spectra of much lower redshift. In three of them the QSO luminosity is extended asymmetrically, and there is a foreground cluster of galaxies with sizes and magnitudes consistent with the absorption redshift. In the fourth case, the absorption redshift is suspect, and there is neither a galaxy cluster nor a resolved QSO image. It is concluded that the absorption spectra arise in the foreground galaxy clusters, and that the QSOs are, therefore, candidates for gravitational lensing.
