Models for Radiation Emitted by Galaxies¶
There are three main ways to model the radiation emitted by galaxies, governed largely by whether or not pop_sed_model
is True
or False
.
pop_sed_model=True
¶
In this case, we’re assuming that the source population is well-described by a single spectral energy distribution (SED). The relevant parameters are:
pop_sed
pop_yield
pop_yield_units
pop_Emin
pop_Emax
pop_EminNorm
pop_EmaxNorm
See the Parameter Listing page for information about the possible values of these parameters.
pop_sed_model=False
¶
In this case, the SED of sources will not be considered in detail. Instead, the amount of radiation emitted in the Lyman-Werner, Lyman-continuum, and X-ray bands is determined by independent parameters.
Option 1: pop_fstar
is not None
In this case, the following parameters are fair game:
pop_Nion
pop_fesc
pop_Nlw
pop_cX
pop_fX
Option 2: pop_fstar
is None
In this case, only three parameters are relevant:
pop_xi_LW
pop_xi_UV
pop_xi_XR
