The TNG50-SKIRT Atlas: post-processing methodology and first data release

Understand

Galaxy morphology is a powerful diagnostic to assess the realism of cosmological hydrodynamical simulations.

• Determining the morphology of simulated galaxies requires the generation of synthetic images through 3D radiative transfer post-processing that properly accounts for different stellar populations and interstellar dust attenuation.
• We use the SKIRT code to generate the TNG50-SKIRT Atlas, a synthetic UV to near-infrared broadband image atlas for a complete stellar-mass selected sample of 1154 galaxies extracted from the TNG50 cosmological simulation at $z=0$.
• The images have a high spatial resolution (100 pc) and a wide field of view (160 kpc).
