Abstract
To help understand the effects of galaxy interactions on star formation, we\nanalyze Spitzer infrared and GALEX ultraviolet images of the interacting galaxy\npair Arp 82 (NGC 2535/6), and compare to a numerical simulation of the\ninteraction. We investigate the UV and IR properties of several star forming\nregions (clumps). Using the FUV/NUV colors of the clumps we constrain the ages.\nThe 8 micron and 24 micron luminosities are used to estimate the far-infrared\nluminosities and the star formation rates of the clumps. We investigate\npossible gradients in the UV and IR colors. See Smith et al. (2006a,b) for\nglobal results on our entire interacting sample.\n
