Ultra Diffuse Galaxies in the IC1459 Group from the VEGAS Survey
  Using deep g,r,i imaging from the VEGAS survey, we have searched for ultra
diffuse galaxies (UDGs) in the IC 1459 group. Assuming they are group members,
we identify 9 galaxies with physical sizes and surface brightnesses that match
the UDG criteria within our measurement uncertainties. They have mean colours
of g--i = 0.6 and stellar masses of $\sim$10$^8$ M$_{\odot}$. Several galaxies
appear to have associated systems of compact objects, e.g. globular clusters.
Two UDGs contain a central bright nucleus, with a third UDG revealing a
remarkable double nucleus. This appears to be the first reported detection of a
double nucleus in a UDG - its origin is currently unclear.
