Mapping the Cosmic Web
Dark matter constitutes approximately 85% of the matter in the universe, yet it remains invisible. We provide the computational frameworks to simulate its gravitational influence on visible matter, enabling the reconstruction of the Cosmic Web across billions of light-years.
N-Body Simulations
Tracking the gravitational interaction of billions of discrete particles. These simulations are essential to understand the hierarchical clustering of dark matter halos.
- TreePM and P3M Algorithms
- Petascale particle load balancing
Baryonic Feedback
Simulating how "normal" matter interacts with dark matter halos. We model supernova explosions, stellar winds, and AGN feedback to resolve the galaxy-halo connection.
- Smoothed Particle Hydrodynamics (SPH)
- Radiative cooling and star formation laws
