Cosmological H II regions and the photoionization of the intergalactic medium

The classical H II region problem is generalized to treat the case of a point ionizing-radiation source in a gas expanding cosmologically in a Friedmann-Robertson-Walker universe, applying a cosmological generalization of the static Stromgren radius to obtain the time dependence of the radius and pe...
