Four models for our calculation of cosmic reionization.
| Model | Escape fraction (fesc) |
||
|---|---|---|---|
| Stripped stars | Massive stars | AGN | |
| Standard | Eq. (2) | Eq. (3) | 80% |
| High-fesc | 80% | 20% | 80% |
| Low-fesc | 30% | 5% | 80% |
| Combination | 80% | 5% | 80% |
Notes. They differ from each other by the assumed escape fraction for the considered ionizing sources. We use the models presented in Paper III to represent the ionizing emission from stripped stars, the predictions from STARBURST99 for the contribution from massive main-sequence and WR stars (Leitherer et al. 1999, 2010), and the emissivity presented in Puchwein et al. (2019) to represent the ionizing emission from AGN. For details, see Sect. 2.1.
