Arp 240 is a galaxy merger between two spiral galaxies NGC 5257 and 5258. The merger is in an early stage and a noticeable bridge connects the galaxies through their arms. Arp 240 has off-nuclear starbursts in both galaxies that make up most of the energy in the pair. We would be mapping emission associated with supernovae or a compact AGN and then could use the radio luminosity to calculate a star formation rate. Data already exists in the B and I band.
