Can Old Galaxies at High Redshifts and Baryon Acoustic Oscillations Constrain H 0 ?
A new age-redshift test is proposed in order to constrain H0 with basis on the existence of old high redshift galaxies (OHRG). As should be expected, the estimates of H0 based on the OHRG are heavily dependent on the cosmological description. In the flat concordance model (ΛCDM), for example, the value of H0 depends on the mass density parameter ΩM = 1−ΩΛ. Such a degeneracy can be broken trough...
متن کاملMeasuring the speed of light with baryon acoustic oscillations.
In this Letter, we describe a new method to use baryon acoustic oscillations (BAO) to derive a constraint on the possible variation of the speed of light. The method relies on the fact that there is a simple relation between the angular diameter distance (D(A)) maximum and the Hubble function (H) evaluated at the same maximum-condition redshift, which includes speed of light c. We note the clos...
متن کاملBaryon Acoustic Oscillations
Observations of baryon acoustic oscillations (BAO) in the clustering of galaxies offer an attractive method for setting cosmological constraints. The physics of the BAO production is well understood, and it is hard to imagine that galaxy formation processes will significantly distort this large-scale signal. The large volume of the Universe and redshift range probed by proposed SKA surveys will...

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...
