yaw.cosmology.CustomCosmology#

class yaw.cosmology.CustomCosmology[source]#

Bases: ABC

Meta-class that defines the interface for custom cosmologies.

Custom cosmology must either be an astropy cosmological model or must be a subclass of this meta-class to be compatible with yet_another_wizz.

Methods

`__init__`()
`angular_diameter_distance`(z)	Compute the angular diameter distance at the given redshift.
`comoving_distance`(z)	Compute the comoving distance at the given redshift.

abstract angular_diameter_distance(z: ArrayLike) → ArrayLike[source]#

Compute the angular diameter distance at the given redshift.

Parameters:: z – A single or an array of redshifts.
Returns:: Float or numpy array with angular diameter distance in Mpc for given input redshifts.

abstract comoving_distance(z: ArrayLike) → ArrayLike[source]#

Compute the comoving distance at the given redshift.

Parameters:: z – A single or an array of redshifts.
Returns:: Float or numpy array with comoving distance in Mpc for given input redshifts.
