I am an Associate Professor at the Department of Astronomy and Theoretical Physics at Lund University, Sweden. Our group’s research is focused on the formation and evolution of galaxies in a cosmological context. Using state-of-the-art computer simulations, we explore a wide range of topics, including how galaxies form in dark matter halos, the physics of galaxy mergers, star formation in the interstellar medium, stellar feedback processes, and the origins of galactic outflows.

Galaxy formation

Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. To understand the origins of these trends, we have carried out and dissected a new high resolution cosmological of a Milky Way-like galaxy, VINTERGATAN. (Vintergatan is the Swedish word for Milky Way, literally The Winter Street)

Simulation details and results in:

  • Agertz et al. (2020): VINTERGATAN I: The origins of chemically, kinematically and structurally distinct discs in a simulated Milky Way-mass galaxy
  • Renaud et al. (2020): VINTERGATAN II: the history of the Milky Way told by its mergers
  • Renaud et al. (2020): VINTERGATAN III: how to reset the metallicity of the Milky Way
