How do galaxies transform from blue, star-forming spirals to red, quiescent early-type
galaxies? To answer this question, we analyzed a set of 26 gas-rich, shocked post-starburst
galaxies with Hubble Space Telescope (HST) imaging in B, I, and H bands and Sloan Digital
Sky Survey (SDSS) i-band imaging of similar depth but lower resolution. We found that post-
starbursts in our sample have intermediate morphologies between disk-and bulge-

Abstract
How do galaxies transform from blue, star-forming spirals to red, quiescent early-type galaxies? To answer this question, we analyzed a set of 26 gas-rich, shocked post-starburst galaxies with Hubble Space Telescope (HST) imaging in B, I, and H bands and Sloan Digital Sky Survey (SDSS) i-band imaging of similar depth but lower resolution. We found that post-starbursts in our sample have intermediate morphologies between disk-and bulge-dominated (S�rsic
