Universe Operators

Class providing operators that act on universe objects—top-level transformations applied to a fully-evolved Galacticus universe (containing the complete set of merger trees and their galaxies) prior to or after model evolution. Universe operators can perform global post-processing steps such as computing derived statistics, writing supplementary output, or modifying global properties. The interface provides a single operate method that receives the universe object and performs whatever transformation the implementation requires.

Default implementation: universeOperatorIdentity

Methods

operate → void

Operate on the universe.

  • type(universe), intent(inout) :: universe_

universeOperatorIdentity

An identity operator on universes.

(Default implementation)

Parameters

  • [redshift] (default 0.0d0) — The redshift at which the transfer function is defined.

universeOperatorIntergalacticMediumStateEvolve

An operator on universes which attaches hooks to compute evolution of the intergalactic medium.

Methods

  • stateSet — Set the state of the IGM state class up to the given time index.

Parameters

  • [timeCountPerDecade] (default 10) — The number of bins per decade of time to use for calculations of the properties of the universe.

  • [redshiftMinimum] (default 0.0d0) — The minimum redshift to use in calculations.

  • [redshiftMaximum] (default 400.0d0) — The maximum redshift to use in calculations.
