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
