I started a huge task (built on Blanton's "gmosaic_make" code that combines GALEX AIS images automatically) to create near-ultraviolet images of galaxies in the SDSS main sample whose optical colors suggest star-formation within the last Gyr. A quick inspection suggests that the K+A galaxies (those that are deficient in emission-line luminosity) also have lower ultraviolet, but I am not close to showing that post-starburst galaxies can be identified ab initio with GALEX imaging. That's the hope.
