| Abstract |
We examine the inner structure of the polar ring galaxies UGC 7576, NGC
2685, and NGC 3718 in U, B, V, and R with images from the WIYN 3.5 meter
telescope. Residual images reveal the presence of a luminous, warped
disk-like structure in the central host of UGC 7576 and NGC 2685, which
is consistent with an S0 morphology. Color maps indicate a B-R color
difference in UGC 7576 and a U-B color difference in NGC 2685 between
the central host and the polar ring. This provides an indication of a
difference in age of stellar populations in the two components of these
polar ring galaxies. Star formation can be traced across much of NGC
3718 from the presence of blue clumps and clusters of younger stars. We
discuss the implications of these results and their role in shaping
future studies of polar-ring galaxies using high resolution optical
images from HST and infrared observations. This work was supported by
the National Science Foundation's REU program and the Department of
Defense's ASSURE program through NSF Award AST-0453442. |
