Mapping the expansion of the Universe gives clues to the underlying physics causing the recently discovered acceleration of the expansion, and enables discrimination among cosmological models. We examine the utility of measuring the rate of expansion, $H(z),$ at various epochs, both alone and in combination with distance measurements. Because of parameter degeneracies, it proves most useful as a complement to precision distance-redshift data. Using the baryon oscillations in the matter power…

Measuring the cosmic evolution of dark energy with baryonic oscillations in the galaxy power spectrum
We use Monte Carlo techniques to simulate the ability of future large high-redshift galaxy surveys to measure the temporal evolution of the dark energy equation of state w(z), using the baryonic
Constraining the evolution of dark energy with a combination of galaxy cluster observables
We show that the abundance and redshift distribution (dN/dz) of galaxy clusters in future high-yield cluster surveys, combined with the spatial power spectrum [P{sub c}(k)] of the same clusters, can
Observational probes of cosmic acceleration
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of “dark energy” with exotic physical
Constraining dark energy via baryon acoustic oscillations in the (an)isotropic light-cone power spectrum
Context. The measurement of the scale of the baryon acoustic oscillations (BAO) in the galaxy power spectrum as a function of redshift is a promising method to constrain the equation-of-state
Correlation Function in Deep Redshift Space as a Cosmological Probe
Recent developments in galaxy surveys enable us to investigate the deep, high-redshift, universe. We quantitatively present the physical information extractable from the observable correlation
Baryon oscillations and dark‐energy constraints from imaging surveys
Baryonic oscillations in the galaxy power spectrum have been studied as a way of probing darkenergy models. While most studies have focused on spectroscopic surveys at high redshift, large
Searching for modified gravity with baryon oscillations : From SDSS to wide field multiobject spectroscopy (WFMOS)
We discuss how the baryon acoustic oscillation (BAO) signatures in the galaxy power spectrum can distinguish between modified gravity and the cosmological constant as the source of cosmic
Measuring Baryon Acoustic Oscillations with Millions of Supernovae
Since Type Ia supernovae (SNe) explode in galaxies, they can, in principle, be used as the same tracer of the large-scale structure as their hosts to measure baryon acoustic oscillations (BAOs). To
Mapping the cosmological expansion
The ability to map the cosmological expansion has developed enormously, spurred by the turning point one decade ago of the discovery of cosmic acceleration. The standard model of cosmology has
Universal fitting formulae for baryon oscillation surveys
The next generation of galaxy surveys will attempt to measure the baryon oscillations in the clustering power spectrum with high accuracy. These oscillations encode a preferred scale which may be
