Hydrodynamical simulations in f(R) gravity using Illustris-TNG find observable 20% effects on high-z HI and stellar power spectra exceeding SKA errors, plus changes in disc galaxy formation.
Below we give an overview of the TNG model and f(R)-gravity, and introduce the new modi- fied gravity solver
