Cosmic Reionization and the 21-cm signal: Comparison between an analytical model and a simulation

20 Aug 2007Mario G. SantosAlexandre AmblardJonathan PritchardHy TracRenyue CenAsantha Cooray

We measure several properties of the reionization process and the corresponding low-frequency 21-cm signal associated with the neutral hydrogen distribution, using a large volume, high resolution simulation of cosmic reionization. The brightness temperature of the 21-cm signal is derived by post-processing this numerical simulation with a semi-analytical prescription... (read more)
