We make available some of the computer codes that we have developed in our group and with our collaborators. Enjoy!

  • Cosmology Routine Library (CRL) in Fortran: Library of useful routines for cosmological quantities
  • lognormal_galaxies: Log-normal simulation of the distribution of galaxies in real and redshift space
    • Reference: A. Agrawal, R. Makiya, C.-T. Chiang, D. Jeong, S. Saito, and E. Komatsu, arXiv:1706.09195
  • lognormal_lens: Log-normal simulation of the weak lensing convergence fields
  • class_sz: Angular power spectrum of the thermal Sunyaev-Zeldovich effect, which supersedes the “szfast” code in the CRL. This code is an add-on to a public Boltzmann solver CLASS
    • Reference: B. Bolliet, B. Comis, E. Komatsu, and J. F. Macias-Perez, arXiv:1712.00788
  • Spectrum Reconstructor: Web tool to compute the covariance matrix of initial tensor power spectra in bins of wavenumbers, given observational specifications of the CMB B-mode polarisation
