Fig. 7.
Relative contribution of ionizing photons from stripped stars (dark blue), massive stars (light blue), and AGN (beige) to the photon budget that caused hydrogen reionization. Stripped stars contributed about 20% of the H I-ionizing photons, see Sect. 4. This figure shows the results from our standard model, for which reionization is complete at z = 6.5 when stripped stars are included (see Tables 1 and 2).
