My research focusses on dynamical processes in the Universe, including

  • the structure and formation of dark matter halos
  • the formation and evolution of galaxies
  • the structure of the multi-phase, turbulent interstellar medium and
  • the formation of stars and stellar clusters.

Many physical processes in the Universe are highly non-linear and coupled in a complex way. A deep understanding of the dynamical Universe often requires detailed numerical simulations, coupled with sophisticated data analysis and visualisation. We are therefore also developing new software and data visualisation tools.

 


 


 Miscellaneous

 

 

 

 The computational astrophysics group depends on strong hydrodynamical codes to perform high resolution and long term numerical simulations. One important task is to continue to revise and extend existing hydrodynamical codes. This includes implementing new numerical methodes and new physics modules to allow faster and more detailed simulations. Implementing and exploring new simulation methods like GPU based codes is another part of our work. Finally, Visualisation especially for large data sets also plays an important role and requires efficient codes.
