Galaxies in Collision: NGC 2207 & IC 2163
Abstract
We propose to observe a pair of relatively nearby colliding galaxies: NGC 2207 & IC 2163. This particular galaxy pair, at 38 Mpc, will nicely complement the diversity of collisional galaxy morphologies studied thus far with Chandra. Collisions between galaxies are known to produce high rates of star formation and the concomitant generation of highly luminous X-ray sources, including ultraluminous X-ray sources. We combine existing Galex FUV and Spitzer 24 micron images to generate star formation rate images that indicate where we expect to find luminous X-rays in these colliding galaxies. With the Chandra observations we will be able to more quantitatively, and with spatial resolution, probe the relation between SFRs and the production of very luminous X-ray sources.
