An instance of a Cosmology subclass specifies the cosmology related parameters of the simulated model, including the redshift at which the model coordinate frame is assumed to reside, as well as the spatial geometry and expansion behavior of the universe.

This function returns the angular-diameter distance \(d_\mathrm{A}(z)\), which converts a proper transverse separation \(\mathrm{d}l\) to the corresponding observed angular separation \(\mathrm{d}\psi\),
\[ \mathrm{d}\psi = \frac{\mathrm{d}l}{d_\mathrm{A}(z)}. \]
Implemented in FlatUniverseCosmology, and LocalUniverseCosmology.

pure virtual |
This function returns the luminosity distance, which converts a total luminosity \(L_\mathrm{tot}\) to the corresponding observed total flux \(F_\mathrm{tot}\),
\[ F_\mathrm{tot} = \frac{L_\mathrm{tot}}{4\pi\,d_\mathrm{L}^2(z)} \]
or a neutral-style monochromatic luminosity \(\lambda L_\lambda\) to the corresponding observed neutral-style flux,
\[ (1+z)\lambda \, F_\lambda[(1+z)\lambda] = \frac{\lambda L_\lambda[\lambda]}{4\pi\,d_\mathrm{L}^2(z)} \]
where \(\lambda\) is the emitted wavelength and \((1+z)\lambda\) is the observed wavelength.
Implemented in FlatUniverseCosmology, and LocalUniverseCosmology.

This function returns the redshift at which the model resides, or zero if it resides in the Local Universe.
Implemented in FlatUniverseCosmology, and LocalUniverseCosmology.

pure virtual |
This function returns the relative expansion rate of the universe, \(\dot{a}/a\), where \(a\) is the dimensionless scale factor. The relative expansion rate has units of \(\mathrm{s}^{-1}\).
Implemented in FlatUniverseCosmology, and LocalUniverseCosmology.
