Trident is a Python package for creating synthetic absorption-line spectra from astrophysical hydrodynamics simulations. It utilizes the yt package to read in simulation datasets and extends it to provide realistic synthetic observations appropriate for studies of the interstellar, circumgalactic, and intergalactic media.
