GalCraft: Building integral-field spectrograph data cubes of the Milky Way

GalCraft is a flexible software to create mock IFS observations of the Milky Way and other hydrodynamical/N-body simulations. It is entirely written in Python3 and conducts all the procedures from inputting data and spectral templates to the output of IFS data cubes in fits format.

The produced mock data cubes can be analyzed in the same way as real IFS observations by many methods, particularly codes like Voronoi binning (Cappellari & Copin 2003), Penalized Pixel-Fitting (pPXF, Cappellari & Emsellem 2004; Cappellari 2017, 2023), line-strength indices (e.g., Worthey 1994; Schiavon 2007; Thomas et al. 2011; Martín-Navarro et al. 2018), or a combination of them (e.g., the GIST pipeline, Bittner et al. 2019).

An elaborate, Python-native parallelization is implemented and tested on various machines from laptops to cluster scales.
