NumCosmoDistanceconformal_time

Declaration [src]

gdouble
nc_distance_conformal_time (
  NcDistance* dist,
  NcHICosmo* cosmo,
  const gdouble z
)

Description [src]

This function computes the cosmological conformal time $\eta(z)$ defined as $$ \eta(z) = \int_z^\infty \frac{dz}{E(z)} \, . $$.

Parameters

cosmo

Type: NcHICosmo

A NcHICosmo.

The data is owned by the caller of the method.
z

Type: const gdouble

Redshift $z$.

Return value

Type: gdouble

$\eta(z)$.
