NumCosmoWindowGaussian
Description [src]
class NumCosmo.WindowGaussian : NumCosmo.Window
{
/* No available fields */
}A gaussian window function.
This object implements the NcWindow class for a Gaussian window function.
The gaussian window function in the real space is defined as, \begin{equation} W_G(r, R) = (2 \pi R^2)^{-3/2}\exp \left( \frac{-r^2}{2 R^2} \right). \end{equation} The mass enclosed within the volume selected by this window function is $$M_G(R) = (2\pi)^{3/2}\bar{\rho}(z) R^3 \, ,$$ where $\bar{\rho}(z)$ is the mean density of the universe at redshift $z$.
When the function nc_window_eval_fourier() is applied,
it returns the gaussian window function in the Fourier space,
\begin{equation}
W_G(k, R) = \exp \left( \frac{-k^2 R^2}{2} \right).
\end{equation}
and nc_window_deriv_fourier() returns the derivative with
respect to R of the gaussian window function in the Fourier space,
\begin{equation}
\frac{dW_G(k, R)}{dR} = -k^2 R \exp \left( \frac{-k^2 R^2}{2} \right).
\end{equation}
The derivative with respect to R in real space is performed by nc_window_eval_realspace().
Instance methods
Methods inherited from NcWindow (5)
nc_window_deriv_fourier
This function returns the derivative with respect to R of the window function
in the Fourier space.
nc_window_eval_fourier
This function computes the window function in the Fourier space.
nc_window_eval_realspace
This function computes the window function in real space.
nc_window_free
Atomically decrements the reference count of wf by one. If the reference count drops to 0,
all memory allocated by wf is released.
nc_window_volume
This function returns the volume of the region (with radius 1) defined by the window function.
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.
