ProSpect: Generating Spectral Energy Distributions with Complex Star
  Formation and Metallicity Histories
  We introduce ProSpect, a generative galaxy spectral energy distribution (SED)
package that encapsulates the best practices for SED methodologies in a number
of astrophysical domains. ProSpect comes with two popular families of stellar
population libraries (BC03 and EMILES), and a large variety of methods to
construct star formation and metallicity histories. It models dust through the
use of a Charlot & Fall attenuation model, with re-emission using Dale
far-infrared templates. It also has the ability to model AGN through the
inclusion of a simple AGN and hot torus model. Finally, it makes use of
MAPPINGS-III photoionisation tables to produce line emission features. We test
the generative and inversion utility of ProSpect through application to the
Shark galaxy formation semi-analytic code, and informed by these results
produce fits to the final ultraviolet to far-infrared photometric catalogues
produces by the Galaxy and Mass Assembly Survey (GAMA). As part of the testing
of ProSpect, we also produce a range of simple photometric stellar mass
approximations covering a range of filters for both observed frame and rest
frame photometry.
