Closing in on a Short-Hard Burst Progenitor Constraints from Early-Time Optical Imaging and(32)

The localization of the short-duration, hard-spectrum GRB 050509b was a watershed event. Thanks to the nearly immediate relay of the GRB position by Swift, we began imaging the GRB field 8 minutes after the burst and continued for the following 8 days. No
