We investigate the 21 cm signals from the UV ionizing sources in the reionization epoch. The formation and evolution of 21 cm emission and absorption regions depend essentially on the kinetics of photons in the physical and frequency spaces. To solve the radiative transfer equation, we use the WENO algorithm, which is effective to capture the sharp ionization profile and the cut-off at the fron...
متن کاملWill point sources spoil 21 cm tomography ?
21 cm tomography is emerging as a promising probe of the cosmological dark ages and the epoch of reionization, as well as a tool for observational cosmology in general. However, serious sources of foreground contamination must be subtracted for experimental efforts to be viable. In this paper, we focus on the removal of unresolved extragalactic point sources with smooth spectra, and evaluate ho...
متن کاملStudying the sources of cosmic reionization with 21-cm fluctuations
We explore the ability of measurements of the 21-cm power spectrum during reionization to enable the simultaneous reconstruction of the reionization history and the properties of the ionizing sources. For various sets of simulated 21-cm measurements, we perform maximum likelihood fits in order to constrain the reionization and galaxy formation histories. We employ a flexible six-parameter model...
متن کاملRedshifted 21-cm Signals in the Dark Ages
We have carried out semianalytic simulations to build redshifted 21-cm maps in the dark ages. An entropy-floor model is adopted for planting protogalaxies in simulated minihaloes. The model allocates gas quantities such as baryonic mass and temperature to every N -body particle and extensively exploits the particle nature of the data in the subsequent analysis. We have found that the number den...
متن کاملPolarization Signals of the 21 cm Background from the Era of Reionization
While emission and absorption lines of the 21 cm spin-flip transition of neutral Hydrogen are intrinsically unpolarized, a magnetic field creates leftand right-handed polarized components through the Zeeman effect. Here we consider the resulting polarization of the redshifted 21 cm background from the intergalactic medium before reionization. The polarization is detectable in regions with a str...
