Generating spectra¶
Synthesizer currently supports the generation of spectra for both stellar populations and AGN.
Generation of spectra for each component in a galaxy requires an emission model defining the different spectra to be generated.
With a model in hand, all that needs to be done is pass that model to the get_spectra method on a component or galaxy.
This will generate Sed objects (see here for an overview) and attach them to the component / galaxy.
Integrated vs Particle¶
Synthesizer enables the generation of both integrated spectra (a single spectra per component / galaxy) or “per–particle” spectra (a spectra for each individual particle). The latter of these is (unsurprisingly) only applicable for particle components (particle.Stars and particle.BlackHoles), while the former can be generated for both parametric and particle components. Additionally, galaxy level spectra are, by definition, integrated.
Integrated spectra are generated by get_spectra methods, and store the resultant spectra in a dictionary called spectra on the component / galaxy.
Any particle based components also provide the get_particle_spectra method, which will produce per–particle spectra, and store the generated spectra in a dictionary called particle_spectra on the component.
In the linked docs we demonstrate how, using EmissionModels in conjunction with these methods, you can generate component and galaxy spectra.
