| Abstract: |
The compact group of galaxies ``Seyfert's Sextet'' shows irregularly shaped soft X-ray morphology. In order to understand its origin, we have obtained a deep optical (VR + I) image of the group. Our image shows that a faint envelope surrounds the member galaxies. We find that optical and soft X-ray images are significantly similar in morphology. This similarity provides direct morphological evidence that the dark matter in Seyfert's Sextet was originally associated with the individual galaxies and is now spreading out around the group. |
