Scientific paper

We report evidence for large amounts of dust around post-starburst K+A galaxies. Using NVO facilities, we searched for circumgalactic dust expected to be produced and ejected by massive starburst galaxies on a timescale of a few 100 Myr. The dust was detected through the extinction and reddening of galaxies in the background of K+A galaxies. We found that the average extinction and reddening in the background of 200 Kpc from the center of a K+A galaxy is 0.3 mag in the g band and 0.1 mag in the g-r color, respectively. This is a surprisingly large amount of extinction, and suggests that mechanisms such as metal-enriched winds and tidal tails are efficient at transporting dust to large radii during galaxy mergers, and that the dust can persist for 1 Gyr if not longer.
