Scientific paper
We propose high resolution imaging with the Planetary Camera (PC) of a nearly complete sample (10/12) of the nearest infrared quasars that have been discovered in the IRAS database. These objects appear to represent a critical evolutionary link between ultraluminous infrared galaxies and optical QSOs. Ground-based observations suggest that these objects contain a mixture of nuclear starburst and AGN components, both of which are fueled by a tremendous reservoir of molecular gas that has been funneled into the merger nucleus during the merger of two gas- rich galaxies. PC images in B and I filters will be used to trace the distribution of different stellar populations, to separate out point source components, to trace the effects of the merger process in these galaxies, and to search for the presence of bars or other such structures that may serve to funnel gas or stars into a putative central AGN. (Note: This proposal was awarded time in the first call for Cycle 1, but was subsequently given supplemental status in the reassessment phase to carry out a limited search for double nuclei, but it was never executed. A limited search for double nuclei in 5 objects was carried out with FOC/96 in Cycle 2.)
