Outside the Local Group, the nearest concentration of largeglobular cluster systems is in the Fornax cluster. Based ondifferences in host galaxy morphologies, we expect that theseglobular cluster systems should show differences which wouldbear on our understanding of the role of mergers, tidalencounters, cooling flows, and initial collapse in theformation and evolution of globular clusters and clustergalaxies. We propose to obtain WFPC2 images of the cores ofthe cD galaxy NGC 1399, the merger candidate NGC 1316, and twomore normal ellipticals. The superior resolution of WFPC2will permit detection and photometry of globular clusters inthe bright and crowded centers of our sample galaxies as wellas enable improved discrimination between globular clustersand background galaxies. We will measure colors, surfacedensities, and structural parameters of these globulars and,by comparing with control fields and ground-based imaging,measure system core radii, look for radial color gradients,and search for young, blue clusters of the type discovered inNGC 1275. We will also determine globular cluster luminosityfunctions to about 3 magnitudes past the expected luminositypeak, enabling us to i) test the ``universality'' of globularcluster luminosity functions, ii) look for environmentalinfluences, and iii) improve estimates for the distance to theFornax cluster. Followup spectroscopy of young or otherwiseinteresting objects will be carried out using the Kecktelescope.
