NumCosmoTransferFuncEHNoBaryon
Description [src]
final class NumCosmo.TransferFuncEHNoBaryon : NumCosmo.TransferFunc
{
/* No available fields */
}Eisenstein-Hu fitting function for the transfer function with no baryons.
This object implements the Eisenstein-Hu (1998) zero-baryon (“no-wiggle”) fitting function, which smooths over the baryon acoustic oscillations while retaining the broadband shape: \begin{equation} T_0(k) = \frac{L_0}{L_0 + C_0\,q^2}, \qquad q = \frac{k\,\theta^2}{\Gamma_\mathrm{eff}}, \end{equation} where $\Gamma_\mathrm{eff}$ is an effective shape parameter built from the matter (#nc_hicosmo_Omega_m0) and baryon (#nc_hicosmo_Omega_b0) densities and $\theta = T_\mathrm{CMB}/2.7$.
For the full definitions of $L_0$, $C_0$, and $\Gamma_\mathrm{eff}$, see the theoretical background page (Zero-Baryon Variant section): Eisenstein–Hu Transfer Function. Reference: Eisenstein and Hu (1998).
Constructors
nc_transfer_func_eh_no_baryon_new
Creates a new NcTransferFunc of the NcTransferFuncEHNoBaryon type.
Instance methods
Methods inherited from NcTransferFunc (5)
nc_transfer_func_eval
The transfer function tf value at mode (wavenumber)
kh (in $Mpc^{-1}$ units) with model cosmo.
nc_transfer_func_free
Atomically decrements the reference count of tf by one. If the reference count drops to 0,
all memory allocated by tf is released.
nc_transfer_func_prepare
Prepares the transfer function tf with model cosmo,
such that one can evaluate it (#nc_transfer_func_eval).
nc_transfer_func_prepare_if_needed
Prepares (if necessary) the transfer function tf with model cosmo.
nc_transfer_func_ref
Increases the reference count of tf atomically.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
