Scientific paper

We analyze F555W(V) band Planetary Camera images of NGC 4365, for which ground-based spectroscopy has revealed a misaligned, counter-rotating core. Line profile analysis by Surma indicates that the counter-rotating component has a disk structure. After deconvolution and galaxy modeling, we find photometric evidence, at small radii to support this claim. There is no indication of a central point source or dust lane. The surface brightness profile reveals a steep outer profile and shallow, by not flat, inner profile with the inflection radius occurring at 1.8 sec. The inner profile is consistent with a cusp.
