Class
NumCosmoHaloDensityProfileEinasto
Description [src]
final class NumCosmo.HaloDensityProfileEinasto : NumCosmo.HaloDensityProfile
{
/* No available fields */
}Einasto density profile.
Implements NcHaloDensityProfile with the dimensionless 3D density
\begin{equation}
\hat{\rho}(x) = \exp \left[ - \frac{2}{\alpha} \left( x^\alpha - 1 \right) \right],
\end{equation}
where $x = r/r_s$ and $\alpha$ is the shape parameter
(NcHaloDensityProfileEinasto:alpha) controlling how steeply the slope
changes with radius. The spherical mass has a closed form; the projected
quantities are computed numerically.
For the closed-form spherical mass and references, see the theoretical background page: Halo Density Profiles.

Properties
NumCosmo.HaloDensityProfileEinasto:alpha
Defines how the profile steepens with slope. Typical values range from 0.12 to 0.35 based on N-body simulations (Gao et al. 2008, Dutton & Maccio 2014).
Properties inherited from NcHaloDensityProfile (3)
NumCosmo.HaloDensityProfile:lnXf
Logarithm of the upper limit of the interval where the projected densities are computed $\ln(X_f)$.
NumCosmo.HaloDensityProfile:lnXi
Logarithm of the lower limit of the interval where the projected densities are computed $\ln(X_i)$.
NumCosmo.HaloDensityProfile:reltol
Relative tolerance used in the numerical computations.
