Projects

Auriga Project

The Auriga Project is a large suite of high-resolution magneto-hydrodynamical simulations of Milky Way-sized galaxies, simulated in a fully cosmological environment by means of the ‘zoom-in’ technique. It is simulated with our state-of-the-art hydrodynamic moving mesh code AREPO, and includes a comprehensive galaxy formation model based on the successful cosmological simulation Illustris. We have setup…

Virgo-Consortium

The Virgo Consortium for cosmological supercomputer simulations was founded in 1994 and has developed rapidly into the international collaboration that it is today. The Virgo Consortium has a core membership of about a dozen scientists in the UK, Germany, Netherlands, and Canada. The largest nodes are the Institute for Computational Cosmology in Durham, UK and the…

Millennium Galaxy Catalogues

When published in 2005, the Millennium Run was the largest ever simulation of the formation of structure within the ΛCDM cosmology. It uses 1010 particles to follow the dark matter distribution in a cubic region 500h−1Mpc on a side, and has a spatial resolution of 5h−1kpc. Application of simplified modelling techniques to the stored output…

Illustris-Simulation

The Illustris project is a large cosmological hydrodynamics simulation of galaxy formation, completed in late 2013, using a state of the art moving-mesh code and a comprehensive physical model. Building on several years of effort by members of the collaboration (based mostly at HITS and the Harvard Center for Astrophysics), the Illustris simulation represents an…

TR-33: “The Dark Universe”

The TAP group participates in the Transregional Collaborative Research Centre TRR 33 “The Dark Universe”, funded by the DFG. In the standard cosmological model, normal baryonic matter contributes only roughly 5% to the overall density of our universe, the rest being in the form of dark matter (27%) and dark energy (68%). Whereas dark matter has…

EXAMAG

The EXAMAG project (“Exascale simulations of the evolution of the universe including magnetic fields”) within the SPPEXA network of the DFG aims to take crucial steps towards physically much more self-consistent simulations of cosmic structure formation, beginning soon after the Big Bang and ending with the formation of realistic stellar systems like the Milky Way.…

SFB-881: “The Milky Way System”

The TAP group participates in the Collaborative Research Center (Sonderforschungsbereich, SFB) 881 “The Milky Way System” at Heidelberg University. The research work of SFB 881 revolves around our own galaxy, the Milky Way, a typical spiral galaxy and hence a member of the most common class of massive galaxies in the universe. The scientists involved in the SFB…

EXAGAL

The European Research Council (ERC) has funded the Project EXAGAL “Hydrodynamical Simulations of Galaxy Formation at the Peta- and Exascale” as a Starting-Grant within the European Union’s Seventh Framework Programme for research, technological development and demonstration, for a period of 60 months, starting in February 2013. The project is led by principal investigator Volker Springel,…
