Description
I will summarise results on modelling HI from different hydro simulations using analytical field level model. I will then give an update on the method and the code 'Hi-Fi mocks' to generate arbitrary large 3D HI mocks from smaller hydro-simulations. Finally I will show how robustly one can recover the input cosmology from these mocks using power spectrum and use these results to forecast the cosmological constraints from upcoming 21cm surveys.
