CPT Library: Codes for cosmological perturbation theory

What's new

• Supplemental code to compute the redshift-space cross power spectrum (based on TNS model) is added (SPTcorr_cross_power.tgz). This has been used in the eBOSS (DR16) paper (2020/07/17)
• Supplemental package for redshift-space power spectrum is added. See RegPT page (2017/12/04)
• Python package RESPRESSO is released (2017/08/31)
• New code RegPT is released (2012/08/06)

Codes and packages

RESPRESSO

RESPRESSO is the Python package developed by T. Nishimichi, F. Bernardeau, A. Taruya. The package gives you the predictions of nonlinear matter power spectrum based on a novel method with response function. Download link is here.

RegPT

RegPT is fortran package for fast power spectrum calculations at two-loop order. Click here for download.

Matter power spectrum in real space

• Standard PT (1-loop) : stdPTreal.f

• Standard PT (2-loop) :

  You need Monte Carlo integrator and PT kernel generator:

  • Monte Carlo integrator:
    
    • Monte Carlo code with VEGAS
    • Monte Carlo code with CUBA library
      (you further a need library file, libcuba.a, which can be created from Cuba library )

  • PT kernel generator: kernel_PT.f

• Lagrangian PT (1-loop) : LPTreal.f

• Closure theory : CLAreal.tgz (f77), CLAreal_f90.tgz (f90, MPI implimentation)
  (you further need a library file, libcuba.a, which can be created from Cuba library )
  

  In addition to the above file, a common read file for output data is needed : read_pk_real.f

Matter power spectrum in redshift space

• Standard PT (1-loop) : stdPTred.f

• Lagrangian PT (1-loop) : LPTred.f

• Improved prescription for redshift-space power spectrum based on TNS model :
  • Auto- and cross-power spectra of density and velocity-divergence fields : stdPT2.tgz (standard PT 1-loop),   CLAred.tgz (closure theory)

  • A and B terms for auto-power spectrum: PTcorr.tgz (standard PT 1-loop),   RegPTcorr.tgz (RegPT 2-loop)

  • A and B terms for cross-power spectrum: SPTcorr_cross_power.tgz (standard PT 1-loop)
