Welcome to the GASSPY wiki!

GASSPY (GPU Accelerated Spectra Synthesis in PYthon) is a package to post-process hydrodynamical simulations through the photoionization code Cloudy (https://gitlab.nublado.org/cloudy/cloudy/-/wikis/home) to get emission spectra from a cell by cell level. The code takes two steps:

• Database bulding: Takes the physical quantities such as density, temperature and radiation fluxes for each cell and runs a set of Cloudy models to cover them. We attempt to not run one model for each cell, but rather group the cells in phase space and run a single model per group.
• Radiative transfer: Takes the database generated in the previous step and performs a raytracing and radiative transfer step to generate a set of rays with position and spectra information that can then be used as input data to emulate an observation.

NOTE: GASSPY is not complete and therefore not ready for usage. Its only shown here as a demonstration and should not be used for scientific studies as of writing.
