I am mainly interested in the formation and evolution of galaxies in a LCDM universe.
Specifically, my research focuses on
- how feedback processes from stars regulate star formation and dynamical evolution of gas in a cosmological context, in conjuction with the properties of outflowing gas from high-z galaxies,
- how many photons escape from dwarf galaxies in the young universe,
- how disk galaxies form in a LCDM universe where galaxy mergers are frequent,
For these purposes, I use (radiation) hydrodynamics simulations with AMR (RAMSES or Enzo).
I have been developing stellar feedback models that can capture the momentum transfer as realistically as possible.
