The dark matter halos of Andromeda’s satellite galaxies
The Astrophysics group at the University of Surrey invites applications for one funded PhD position to start in October 2020 for a period of three years.
Start date1 October 2020
Funding sourceDCAS studentship
The studentship will cover tuition fees in full and it will provide a PhD stipend at the standard STFC level of approx c. £14000 per annum, as well as a budget for training activities (e.g. conferences).
The true nature of dark matter, which makes up roughly 85% of all the matter in the Universe, is one of the key outstanding problems in astronomy and particle physics. In this PhD project, the student will use exquisite data for the dwarf galaxies of Andromeda (M31) to place constraints on the properties of dark matter. The student will combine dynamical data for M31 dwarf galaxies with deep star formation histories from a new Hubble Space Telescope survey, to measure the central mass profiles of approximately 30 dwarf galaxies in Andromeda. These objects are particularly interesting, as they are overwhelmingly dominated by dark matter. This PhD project will allow us to address:
- Whether the dark matter profiles of M31 dwarf galaxies are consistent with steep central cusps, or lower density cores.
- Whether the star formation histories of M31 dwarf galaxies correlate with their central densities, as seen for some Milky Way dwarfs.
- Whether star formation heating of dark matter is a viable explanation for discrepancies between simulations of dwarf galaxies, and our observations.
