摘要：

Images are discussed of six QSOs at z=2.3, one QSO-like IRAS source at z=2.3, and one QSO at z=1.1, taken with resolution 0.6 to 0.9 arcsec. Five of the QSOs are radio-quiet. All QSOs except one are just resolved, while the IRAS source has definite structure. In some cases, part of the QSO fuzz appears to be a close companion rather than a concentric host galaxy. The luminosities implied for the hosts or companions are typical of bright galaxies with young hot star populations. Radio-quiet QSOs appear to have host galaxies less luminous, by similar to 2 mag, than radio-loud QSOs. (C) 1995 American Astronomical Society.
