21cmEMUv3 emulates the cylindrical 21cm power spectrum via score-based diffusion and six other 21cmFAST observables via LSTM networks at sub-percent accuracy, then uses the emulator to infer a lower limit on soft-band X-ray luminosity from HERA data.
Conditioning f_coll on tidal eigenvalues from small-box simulations allows low-resolution large-volume reionization runs to recover HI power spectra to within 2-5% on scales k less than 0.5 h/Mpc.
Lumina runs a 500 cMpc radiation-hydrodynamic simulation combining IllustrisTNG galaxy formation with six-bin M1 radiation transport to predict late stellar-driven HI reionization ending around z=4.75 and AGN-driven HeII reionization nearly complete by z=3.
Forecasts show that future 21 cm surveys can deliver moderate constraints on the scale-dependent growth index and HI bias in viable f(R) models.

Conditioning halos on the tidal environment for fast and accurate HI power spectra during reionization
Conditioning f_coll on tidal eigenvalues from small-box simulations allows low-resolution large-volume reionization runs to recover HI power spectra to within 2-5% on scales k less than 0.5 h/Mpc.
