EnzoCosmology.critical_density(z)¶

The density required for closure of the Universe at a given redshift in the proper frame.

Parameters:	z : float Redshift.

Examples

>>> co = Cosmology()
>>> print co.critical_density(0.).in_units("g/cm**3")
>>> print co.critical_density(0).in_units("Msun/Mpc**3")
