In this project, we simulate the distribution of dark matter in our own Milky Way galaxy with unprecedented resolution.
Millennium-XXL
Here we have carried out the largest N-body simulations ever performed, using more than 300 billion particles. The simulation follows the formation history of more than 500 million galaxies in a volume more than 10 billion lightyears across. This allows a reliable study of systematic effects in galaxy formation surveys that try to contrain dark energy.
Aquila
This project seeks clues to spiral galaxy formation through detailed high-resolution simulations of galaxy formation. We carry out full cosmological hydrodynamic simulations both with the SPH code GADGET-3 and the Lagrangian moving-mesh code AREPO.
These simulations follow 10 billion particles each, in volumes of 500 and 100 Mpc/h across, respectively. The simulations have been used to measure detailed merger history trees that also track halo dark matter substructure. This allowed the construction of highly detailed galaxy formation models.
Non-standard dark energy cosmolgies
As part of TR33 "The Dark Universe", we develop new simulation methods for studying non-linear structure formation in non-standard dark energy scenarious. In particular, we consider spatially varying dark energy fields, and non-trivial couplings to the dark matter sector.
