    "body_text": "Weak-lensing forecasts need the way gas and stars reshape matter, but full hydrodynamic simulations are expensive. BIND learns to map dark-matter-only halos to dark matter, gas and stellar fields using 1,024 paired CAMELS simulations spanning cosmology and galaxy-formation parameters. The authors report percent-level mass recovery, radial profiles within roughly 10%, and preserved shape and residual relationships without giving the model halo mass as an input. Applied halo by halo to a 512-cubed-particle volume, it reproduced projected power suppression in minutes on one GPU.",
