6. Future Work

In the time span of ten weeks, I was only able to sractch the surface of polar ring galaxies. There is plenty more to do and learn about these peculiar objects. I will continue to research them with professors Sparke and Gallagher. We have another observation run at KPNO scheduled for the beginning of December 2006. I am also planning on attending the AAS conference in Seattle at the beginning of January 2007. We are hopefully that we will have results from data from the Hubble Space Telescope (HST) and infrared (IR) observations of polar ring galaxies to complement our work by that time.

6.1 Hubble Space Telescope

Our result thus far supports the conjecture that the central host galaxy of UGC 7576 and NGC 2685 are S0-type galaxies. The luminous disk-like structure was only resolvable after the image was filtered. We would like to use higher resolution data to study the inner structure of these two polar ring galaxies. We turn to the Hubble Space Telescope for this purpose. It can achieve resolutions 10 times greater than ground based telescopes. In addition, the higher resolution data from HST has be pre-reduced and calibrated to a set of standard stars. This will allow use to compute total magnitudes and colors for these polar ring galaxies and give us deeper insight into the constituents of these polar ring galaxies.

6.2 Infrared Data

From the color maps of NGC 3718, we saw that this polar ring galaxy contains many star clusters. As stated earlier, we can perform photometry on these star colors and determine the age of NGC 3718. Since the polar ring contains much dust, it would be ideal to use IR data for the photometry of these star clusters since there is less extinction at longer wavelengths. I plan to obtain IR data for NGC 3718 using the 76.2 cm telescope at Leuschner Observatory. Hopefully, the data will have high enough resolution to be useful to our science program.
