THE SENSITIVITY OF FIRST-GENERATION EPOCH OF REIONIZATION OBSERVATORIES AND THEIR POTENTIAL FOR DIFFERENTIATING THEORETICAL POWER SPECTRA

摘要: Statistical observations of the epoch reionization (EOR) power spectrum provide a rich data set for understanding transition from cosmic ‘‘dark ages’’ to ionized universe we see today. EOR have become an active area experimental cosmology, and three first-generation observatories—MWA, PAST, LOFAR—are currently under development. In this paper first quantitative calculation threedimensional sensitivity, incorporating thedesign parameters planned array. This is then used explore constraints these can place on spectrum. The results demonstrate potential upcoming constrain theories structure formation reionization.
