The smallest galaxies as probes of cosmology and galaxy evolution
The smallest galaxies in the Universe provide a unique laboratory for exploring and constraining the properties of dark matter, as well as providing a tool for understanding the processes that are key to galactic evolution on all scales. For this project, the student will use existing data, as well as proposing for new data at international observatories, to make precision measurements of the properties of dwarf galaxies within the Local Group. This will include measuring the masses of nearby dwarf galaxies in order to probe the density of their dark matter halos, and comparing these to predictions of high resolution simulations produced by the Surrey astrophysics group; mapping out the stellar halos of nearby field dwarf galaxies, in order to search for substructure that may inform us both about their evolution and dark matter content; and using the dwarf galaxies of Andromeda as a probe for its evolutionary history.
