Overview
I am participating as a supporting researcher in an ongoing collaborative project that uses large-scale structure simulations to study the relationship between dark matter halo shapes and the cosmic web. My current work focuses on measurement, validation, and visualization support.
Current scope
Because the project is still in progress, this page does not present research results, interpretations, or conclusions.
Role & Scope

Only the role and working tools are summarized here within the currently shareable scope.

My Role & Contributions
- Measured and computed halo shapes from the inertia tensor
- Cross-checked measured values against the catalog
- Visualized simulation slices and projection views
- Computed halo statistics and comparison plots: mass function, two-point correlation function, and shape-mass relation
Methods & Tools
- Language / Libraries: Python, NumPy, SciPy, Matplotlib
- Techniques: inertia-tensor eigendecomposition, MST(cKDTree + Kruskal/Prim), Landy-Szalay estimator, 3D visualization
- Data: Friends-of-Friends(FoF) halo catalog processing
