Bolton, Schiminovich, and I determined empirically that it would have been impossible to detect the SLACS lenses (which were detected as double redshifts in the SDSS spectra) using GALEX. GALEX detects some of the lensing galaxies, but it doesn't look like it detects (strongly) the background lensed galaxies (despite the fact that they are detected because they are strongly star-forming). Oh well.
Bolton and I made some pretty pictures (or relatively pretty) of the SLACS lenses. The challenge was to show the lensing clearly, despite the fact that most of his HST images are only single-band.
