Welcome to SALSA’s documentation!¶
Salsa is an open-source python module that creates a streamlined process to generate synthetic absorber catalogs from galactic simulations. Multiple open-source software projects utilized to achieve this. Accessing simulation data is done using yt. Trident is used to generate synthetic sightlines/lightrays and generate synthetic spectra. Spectacle is used to fit voigt profiles to spectra and extract absorbers.
Observational studies generate large absorber catalogs by studying the absorption line spectra of distant quasars, as their light passes through intervening galaxies. Salsa can generate similar catalogs from cosmological and galactic simulations, allowing research to study these simulations from an observers perspective. This can give new insights into the data as well as help facilitate comparisons and collaboration between simulations and observations
In addition a novel method for extracting absorbers, the SPICE method. This uses cell level data to extract absorbers from a Trident lightray and returns a great deal of information that can be further analyzed.
