Many of these studies were based on GALEX imaging of SDSS galaxies (z~0.1), and were thus limited by its 5\" FWHM. Poor UV resolution left other possibilities for UV excess open, such as the old populations or an AGN. Here we study high-resolution far-ultraviolet HST/ACS images of optically quiescent early-type galaxies with strong UV excess. The new images sho","authors_text":"R.
