- 3D density field (simulated or observational, e.g., DESI/SDSS galaxies). Â
- Resolution: 256 grid for 500 Mpc/h boxes. Â
OutputÂ
- Catalog of void centers and radii. Â
- Fractal dimension \( D \) via box-counting. Â
MethodÂ
- Step 1: Density field estimation (DTFE/Smooth). Â
- Step 2: Void identification (Watershed/VIDE). Â
- Step 3: Fractal analysis (Box-counting/Lacunarity). Â
2. Step-by-Step Implementation
Step 1: Density Field Construction
