Probing Star Formation in Interacting Galaxies Using UV and Mid-IR: The Case of Arp 82

To help understand the effects of galaxy interactions on star formation, we analyze Spitzer infrared and GALEX ultraviolet images of the interacting galaxy pair Arp 82 (NGC 2535/6), and compare to a numerical simulation of the interaction. We investigate the UV and IR properties of several star forming regions (clumps). Using the FUV/NUV colors of the clumps we constrain the ages. The 8 micron and 24 micron luminosities are used to estimate the far-infrared luminosities and the star formation rates of the clumps. We investigate possible gradients in the UV and IR colors. See Smith et al. (2006a,b) for global results on our entire interacting sample.
