摘要
We present broadband images of the optical counterpart to the very strong radio source Hercules A. Through morphological analysis we have been able to identify this source as a cD galaxy with a double nucleus with a nuclear separation of approximately 4 arcsec. We also find a low-luminosity tail coming from the NW end of the cD. There is a slight knot near the center of this extension which may imply that this tail may be a companion galaxy, or perhaps that the knot is just a very faint foreground star. We discuss the morphological and other properties of this radio galaxy.
