The basic approach is to generate synthetic/mock observations from the simulations, apply typical model-fitting approaches, and then see how the model results compare with the properties of the original simulations. Our first paper on this has recently been accepted (https://arxiv.org/abs/1803.07084) and we&#x27;re preparing a second paper looking at emission from dust in new simulations which more realistically treat the cosmological history of galaxies.</p><p><a href="https://hackerpaper.kaipfister.de/p/1803.07084/">Paper and discussion history</a>.
