skypy.power_spectrum.transfer_no_wiggles¶
- skypy.power_spectrum.transfer_no_wiggles(wavenumber, A_s, n_s, cosmology)[source] [edit on github]¶
Eisenstein & Hu transfer function without wiggles. Eisenstein & Hu fitting formula for the transfer function without baryon acoustic oscillation wiggles. This is described in [1] and [2].
- Parameters:
- wavenumber(nk,) array_like
Array of wavenumbers in units of Mpc-1 at which to evaluate the linear matter power spectrum.
- A_s, n_s: float
Amplitude and spectral index of primordial scalar fluctuations.
- cosmologyastropy.cosmology.Cosmology
Cosmology object providing omega_matter, omega_baryon, Hubble parameter and CMB temperature in the present day.
- Returns:
- transfer(nk, ) array_like
Transfer function evaluated at the given wavenumbers for the input primordial power spectrum parameters A_s and n_s, cosmology and kwmap normalization.
