Recent Results in the News

We recently found that the disc of the Milky Way must be tilted relative to the dark matter halo within which it sits.
This work was described in the Oxford University Press Blog here.

We contributed to mapping the three-dimensional structure of the bulge of the Milky Way. The full press release can be found here.
The paper can be found in the Publications tab above.

We showed that black holes must grow efficiently in disc galaxies even when they are evolving in isolation. Check out our press release.

PhD positions

Phd positions are available to work in my group to study the outer regions of disc galaxies and to study the dark matter halo of the Milky Way. The successful applicant will learn how to run and analyse large simulations with gas and star formation to compare with observations. If interested, please contact me directly via email.

The theme of my research is the formation and evolution of galaxies, which I study through simulations, observations and modeling.

Understanding the formation of galaxies — the fundamental building blocks of the universe — with their array of morphologies and scaling relations, is one of the most important problems in cosmology today. Among the questions that need to be addressed are:

  • How do supermassive black holes and nuclear clusters form and evolve?
  • How do galaxies get their shapes? What sorts of structures arise from internal evolution? What sorts of structures result from external evolution? How can the two be distinguished?
  • What is the nature of dark matter? How much dark matter is there, how is it distributed, what is its angular momentum? How can we use the observed structure of galaxies to constrain these properties of dark matter halos?
  • How do stars form in galaxies? How can we use the ages of stars to disentangle the formation of galaxies? How much is this archaeological record disturbed by internal evolution and cannibalism?
