AI-assisted super-resolution cosmological simulations V: Cosmology-aware super-resolution
Xiaowen Zhang, Patrick Lachance, Rupert A. C. Croft +2
We present a cosmology-aware generative model for super-resolution (SR) of cosmological -body simulations in particle phase space. The model jointly generates displacements and…

An AI super-resolution field emulator for cosmological hydrodynamics: the Lyman-α forest
Fatemeh Hafezianzadeh, Xiaowen Zhang, Yueying Ni +4
We extend our super-resolution and emulation framework for cosmological dark matter simulations to include hydrodynamics. We present a two-stage deep learning model to emulate high…
