My research project
Low Surface Brightness FrontierWe aim at studying the faint stellar halos of galaxies as byproducts of hierarchical
assembly processes within the accepted cosmology. These extremely low surface brightness
edges of galaxies encode information about the very smallest mass, lowest density, and
stellar systems that can form, opening a new window on galaxy formation models and
cosmology. In order to achieve our goal we will obtain a clean map of resolved
main-sequence turnoff stars to obtain the ages, metallicities, and star formation
histories. We will hunt for past accretion events, including shells, streams, and
over-densities, similar to those reported at larger mass scales in the Milky Way and M31
but at an unprecedented low surface brightness.

My qualifications
Taking advantage of generations of terrestrial and space-based instruments, the Master of Astronomy and Astrophysics trains students to study the origin, structure, and evolution of planets, stars, star systems, and the universe itself.
Relevant Modules: Binary Stars, Relativity, Star Formation, Galaxies and Cosmology, Observational
Techniques in Astronomy, Research Projects in Theoretical Astrophysics, Interstellar Matter, Stellar Structure and
Evolution, Stellar Atmospheres and Stellar Winds, Radiation Processes in Astronomy.
The focus of the programme was on theoretical and experimental skills in Physics and Mathematics.
