| Abstract |
We present the first results of an investigation into ongoing star
formation within E and S0 galaxies, selected from optical catalogs to be
on the red sequence. Star formation in these spheroidal systems is
traced using ultraviolet imaging from GALEX. We have identified a wide
variety of unanticipated sites of apparent star formation in this
sample, which include clumps, rings, and other structures. In order to
quantify the contributions of these structures to the total UV flux, we
have fit Sersic and/or exponential disk profiles to a subsample of 500
galaxies with high S/N, and compared the residuals of these smooth
component fits to the original galaxy. |
