Recent advances in deep imaging have lead to the discovery of a new, puzzling type of galaxy. Dubbed Ultra-Diffuse Galaxies (UDGs) these are galaxies that are roughly Milky Way sized but extraordinarily faint as they have ~ 10 000 times less stars. To add to the puzzle as to how a galaxy could become so diffuse some such galaxies are found to have extraordinarily large amounts of dark matter (~99.99% - Dragonfly 44) or may even be without dark matter entirely (NGC1052-DF2). My project will make use of state of the art telescopic facilities, namely KCWI on the Keck Telescopes and MUSE on VLT, with the aim of studying what little stellar populations these galaxies do have to provide hints as to how such exotic galaxies might form. I work under the supervision of: Professor Duncan Forbes, Professor Warrick Couch, Dr Anna Ferre-Mateu and Dr Mark Durre. If you have any questions please feel free to send me an email ( and I will be more than happy help you where I may.
