In this talk I present the results of my Master’s Thesis. I summarize the idea of including baryons in KFT and the basics of RKFT. Furthermore, I will summarize the model used to include the effects of ionizing photons into RKFT to describe the Epoch of Reionization. I will present the results of this model in static and expaning spacetime and finally compute the 21cm power spectrum of this model.
