picasso: Painting intracluster gas on gravity-only simulations
Kéruzoré, F.; Bleem, L. E.; Frontiere, N.; Krishnan, N.; Buehlmann, M.; Emberson, J. D.; Habib, S.; Larsen, P.
picasso makes predictions for the thermodynamic properties of the gas in massive dark matter halos from gravity-only cosmological simulations. It combines an analytical model of gas properties as a function of gravitational potential with a neural network predicting the parameters of said model. Written in Python, it combines an implementation of the gas model based on JAX (ascl:2111.002) and Flax (ascl:2504.026), and models that have been pre-trained to reproduce gas properties from hydrodynamic simulations.
