Title: The Evolutionary Paths of Nearby Green Galaxies

Abstract: Red spheroids contain the majority of stars in the local universe, but it was not always so. Many mechanisms have been suggested for the metamorphosis of star-forming disks into quiescent bulges and multiple avenues are likely. Each of these paths yield different predictions for the star-formation patterns and morphologies of fading green galaxies. We propose to obtain CTIO 1m griz imaging for 27 nearby galaxies in the GALEX Nearby Galaxy Survey, the majority of which are green in their NUV-r colors. The spatially-resolved UV-optical color maps and optical morphologies will constrain their merger and star-formation histories, and determine the the evolutionary paths taken by transitional galaxies.
