GalSyn. I. A Forward-modeling Code for Synthetic Galaxy Observations from Hydrodynamical Simulations and the First Data Release from IllustrisTNG
We present Galaxy Synthesizer (GalSyn), a modular and flexible Python package for generating synthetic observations from hydrodynamical galaxy simulations. GalSyn generates synthetic spectrophotometric data cubes for individual galaxies from simulation cutouts, employing a particle-by-particle spectral modeling approac...
