To compute emission line luminosities it is therefore necessary to run Galacticus including the following rest-frame luminosity filters at each redshift of interest: Lyc, HeliumContinuum, OxygenContinuum. This causes the ionizing luminosity for each three species to be computed and output.
Emission line luminosities can then be found using Galacticus's data extraction modules, by simply importing the Galacticus::EmissionLines module. Emission line luminosites (in units of Solar luminosities) can then be accessed as named properties using names such as
which will return the Hα luminosity at z=0. Equivalent properties for disk and spheroid are provided (simply replace "total" with "disk" or "spheroid").
Currently available lines are:
Additionally, if a line is requested as
then the line luminosity is computed under the provided filter, and the luminosity is returned in units of maggies for easy conversion to AB magnitudes.
