Dwarf galaxies are key objects in many cosmological theories, being the most numerous galaxy type in the local universe, the simplest stellar systems that appear to be dominated by dark matter and possible local analogues to the earliest galaxies formed. Due to their intrinsic faintness, however, detailed studies of dwarfs outside of our Local Group are currently limited. This work presents new K-band images of eight dwarf elliptical galaxies in the Fomax Cluster. Morphological and photometric parameters are acquired from the images by surface brightness profile fitting and galaxy modelling techniques. This new infrared data is combined with available optical data to obtain average colours, colour profiles and colour maps of the galaxies.
