Ionized gas emission in SKIRT

I am implementing a module for the SKIRT radiative transfer code to model photoionized gas emission — including diffuse ionized gas (DIG) — in post-processed galaxy simulations. The method uses a compact five-bin characterization of the ionizing radiation field (1–6 Ryd) coupled with precomputed Cloudy lookup tables, enabling efficient generation of spatially resolved emission line maps and synthetic IFU datacubes without a full on-the-fly chemistry solver.

In preparation.
