To illuminate the thermal and reionization history of the intergalactic medium (IGM), we confront cosmological hydrodynamical simulations that post-processed with radiative transfer codes and semi-numerical techniques with the latest data. Those data include observational constraints on the IGM temperature, the statistics of Lyman-alpha emitters and the opacity of the Lyman-alpha forest, as well as with the latest Planck measurements of the Thomson scattering optical depth. This enables us to derive improved constraints on the timing and sources of cosmic reionization. Furthermore, advances in the modelling of the cosmic UV background and the thermal evolution of the IGM will be discussed.
