Nbodykit Cosmology Analyzer

Purpose

Provides expert guidance on nbodykit for large-scale structure analysis, including power spectrum estimation and correlation function calculations.

Capabilities

• Power spectrum estimation (FFT-based)
• Correlation function computation
• Halo finding and mass functions
• Particle mesh operations
• Mock catalog generation
• MPI parallelization

Usage Guidelines

1. Data Loading: Load simulation or survey data
2. Power Spectrum: Estimate power spectra with FFT methods
3. Correlation Functions: Compute two-point correlations
4. Halo Catalogs: Work with halo finder outputs
5. Mock Generation: Create mock galaxy catalogs

Tools/Libraries

• nbodykit
• Corrfunc
• halotools
