Some recent observations of nearby quasars with HST have apparently failed to detect host galaxies. We review the HST observations as well as near infrared ground-based observations of the same objects. We nd that the quasar hosts can be detected in the HST data if they are smoothed suuciently to reveal low surface brightness. The smooth hosts are very diicult to detect with HST but are more ea...

We present optical and near-infrared photometry for a sample of 96 dusty, far-infrared luminous galaxies. We have precise spectroscopic redshifts for all these galaxies yielding a median redshift of < z>= 2.2. The majority, 78, are submillimeter-detected galaxies lying at z = 0.2–3.6, while the remaining 18 are optically-faint μJy radio galaxies at z = 0.9–3.4 which are proposed to be similarly...
