IRAS 09104+4109 is one of the most luminous objects discoveredin the IRAS survey, and has been identified with a large cDgalaxy in a cluster at a redshift of z=0.442. The cD galaxy isin the center of a massive cooling flow. The nuclear spectrumof IRAS 09104+4109 indicates the presence of a dust enshroudedquasar, yet the apparent ionizing flux of the AGN falls shortof that required to produce the infrared luminosity by a largefactor. Within the extended stellar envelope of the cD, thereare a number of faint, yet intrinsically luminous knots.These may be the nuclei of galaxies recently stripped by theirinteraction with the cD galaxy, possibly providing much of thedust and gas associated with the luminous infrared source. Wepropose to use the WFPC2 to observe IRAS 09104+4109 in theF622W, F814W and LRF7220Angstrom filters. With theseobservations we will accurately measure the colors of theluminous knots and search for evidence of the interactionsresponsible for stripping their galactic disks. We will alsoprobe the core of the cD galaxy on a scale of <1 kpc and lookfor both a highly reddened nucleus and a ``cone" of emissionline gas which may mark the polar axis of an obscuring torus.Finally, these data will be used to search for faint,unresolved, blue objects in the halo of IRAS 09104+4109 whichmay be proto-globular clusters formed as a result of theinteractions or out of the cooling flow itself.
