Detailed Description

An instance of the LocalUniverseCosmology class represents a special-case "cosmology" where the simulated model resides at redshift zero. As a result, there is no need to specify the spatial geometry and expansion behavior of the universe.

Constructor & Destructor Documentation

LocalUniverseCosmology()

LocalUniverseCosmology::LocalUniverseCosmology ( )

inlineprotected

Default constructor for concrete Item subclass LocalUniverseCosmology : "the model is at redshift zero in the Local Universe" .

Member Function Documentation

angularDiameterDistance()

double LocalUniverseCosmology::angularDiameterDistance ( ) const

overridevirtual

This function returns the angular-diameter distance \(d_\mathrm{A}(z)\). For this class, it always returns zero, indicating that the model resides in the Local Universe.

Implements Cosmology.

luminosityDistance()

double LocalUniverseCosmology::luminosityDistance ( ) const

overridevirtual

This function returns the luminosity distance. For this class, it always returns zero, indicating that the model resides in the Local Universe.

Implements Cosmology.

modelRedshift()

double LocalUniverseCosmology::modelRedshift ( ) const

overridevirtual

This function returns a zero redshift, indicating that the model resides in the Local Universe.

Implements Cosmology.

relativeExpansionRate()

double LocalUniverseCosmology::relativeExpansionRate ( ) const

overridevirtual

This function returns the present-day relative expansion rate of the universe, often called the Hubble constant, assuming a fixed value of 67.5 (km/s)/Mpc. The function returns this value in SI units, i.e. \(\mathrm{s}^{-1}\).

To configure another value of the present-day relative expansion rate, use the FlatUniverseCosmology class with a redshift of zero and the desired value for the reduced Hubble parameter.

Implements Cosmology.
