Project Description

The biggest problem with current models of galaxy formation is the prediction that large numbers of low mass dark matter haloes form along with the relatively small numbers with masses similar to the Milky Way. The problem is that only relatively small numbers of low luminosity (dwarf) galaxies have been discovered - where are all the small dark matter halos and how can the observations be reconciled with theory? An important issue is that dwarf galaxies are difficult to detect because they are of both low luminosity and also low surface brightness.
There are now many deep CCD surveys of the Universe, initially designed for the determination of other cosmological issues, which can be used to explore the dwarf galaxy low surface brightness Universe. In this project we will explore new image detection and measurement algorithms designed specifically to detect and measure low surface brightness objects in deep large area CCD data and then put the results in context with the predictions from galaxy formation models.
