Abstract:
    We present surface photometry of a sample of 52 galaxies from the
    GALaxy Evolution eXplorer (GALEX) and Two-Micron All-Sky Survey
    (2MASS) data archives. These include 32 normal elliptical galaxies, 
    10 ellipticals with weak LINER or other nuclear activity and 10
    star-forming ellipticals or early-type spirals. We examine the spatial
    distribution of the far-ultraviolet excess in these galaxies, and its
    correlation with dynamical and stellar population properties of the
    galaxies.
