I had one of my two weeklies with Kate Storey-Fisher (NYU) today. As usual, we spent a lot of our time on the big picture. Why are we trying to find translations between hydrodynamical simulations and dark-matter-only simulations? It's because dark-matter-only sims are way cheaper. So we can do lots and lots of those, and then a few hydro sims, and then make translators. Or can we? That's what we're trying to figure out now. We're making use of ideas from our projects on geometric machine learning.
