dsf.modelling.baryons module

Baryonic modifications to halo occupation power-spectrum models.

dsf.modelling.baryons.pk2d_hod_baryonified(cosmo, *, k_array, a_array, f_c=1.0, concentration=None, **hod_kwargs)[source]

Construct HOD power spectra with baryonic concentration rescaling.

Parameters:

  • cosmo (Cosmology) – CCL cosmology.

  • k_array (NDArray[float64]) – Wavenumber grid.

  • a_array (NDArray[float64]) – Scale-factor grid.

  • f_c (float) – Multiplicative concentration rescaling.

  • concentration (Concentration | None) – Optional CCL concentration model. Defaults to Duffy08.

  • **hod_kwargs (Any) – HOD profile parameters.

Returns:

Density-weighted galaxy-matter, galaxy-matter, and galaxy-galaxy spectra.

Return type:
