> Can somebody who knows about this tell me how much of the novelty in this is CS and how much physics? It's a little bit of both. Over the past 5–8 years, some new numerical techniques ("moving mesh") have been developed (or at least first applied in astronomy) for hydrodynamic simulations[0,1]. These new techniques do a much better job of handling fluid instabilities, which can be important for properly simulating the gas in galaxies (which can have a huge range in densities and temperatures). Also, people have developed what they call "cosmological zoom" simulations. In these simulations…
