  • We construct a simple but self-consistent analytic ionization model for rapid exploration of 21 cm power spectrum observables in redshift space. It is fully described by the average ionization fraction xe(z) and H II patch size R(z) and has the flexibility to accommodate various reionization scenarios. The model associates ionization regions with dark matter halos of the number density required to recover xe and treats redshift space distortions self-consistently with the virial velocity of… CONTINUE READING
