Learning the Universe with the 2nd Generation of CAMELS: Varying 35 parameters of the IllustrisTNG model in (50Mpc/h)^3 boxes
This paper presents the second generation of the CAMELS project, featuring 1,192 cosmological simulations with eight times larger volumes than its predecessor to explore a 35-parameter space, demonstrating that while these larger volumes improve neural network-based parameter inference, the gains are sub-linear due to mode coupling and parameter degeneracies.
