Constraints on Fundamental Cosmological Parameters with Upcoming Redshifted 21 Cm Observations
Constraints on cosmological parameters from upcoming measurements with the Mileura Widefield Array—Low Frequency Demonstrator (MWA-LFD) of the redshifted 21 cm power spectrum are forecast assuming a flat ΛCDM cosmology and that the reionization of neutral hydrogen in the intergalactic medium occurs below a redshift of z = 8. We find that observations with the MWA-LFD cannot constrain the underl...
متن کاملConstraints on Fundamental Cosmological Parameters with Upcoming Epoch of Reionization Observations
The first generation of epoch of reionization experiments have the potential to characterize the processes and history of reionization for redshifts 6 < z < 12 by observing the power spectrum of the redshifted 21 cm radiation. These power spectrum observations could also contribute to our knowledge of the underlying cosmology, particularly at redshifts before the effects of reionization strongl...
متن کاملProspects for Redshifted 21-cm Observations of Quasar Hii Regions
The introduction of low-frequency radio arrays over the coming decade is expected to revolutionize the study of the reionization epoch. Observation of the contrast in redshifted 21cm emission between a large H II region and the surrounding neutral IGM will be the simplest and most easily interpreted signature. We assess the sensitivity of three generations of planned low-frequency arrays to qua...
متن کاملLensing Reconstruction Using Redshifted 21 Cm Fluctuations
We investigate the potential of second generation measurements of redshifted 21 cm radiation from the epoch of reionization (EOR) to reconstruct the matter density fluctuations along the line of sight. To do so we generalize the quadratic methods developed for the Cosmic Microwave Background (CMB) to 21 cm fluctuations. The three dimensional signal can be analyzed into a finite number of line o...
متن کاملToward Empirical Constraints on the Global Redshifted 21 Cm Brightness Temperature during the Epoch of Reionization
Preliminary results are presented from a simple, single-antenna experiment designed to measure the all-sky radio spectrum between 100 and 200 MHz. The system used an internal comparison-switching scheme to reduce non-smooth instrumental contaminants in the measured spectrum to 75 mK. From the observations, we place an initial upper limit of 450 mK on the relative brightness temperature of the r...
