Dark energy and curvature from a future baryonic acoustic oscillation survey using the Lyman-{alpha} forest

Journal Article McDonald, Patrick ; Eisenstein, Daniel J. ; Steward Observatory, University of Arizona, 933 North Cherry Avenue, Tucson, Arizona 85121 - Physical Review. D, Particles Fields

We explore the requirements for a Lyman-{alpha} forest survey designed to measure the angular diameter distance and Hubble parameter at 2 < or approx. z < or approx. 4 using the standard ruler provided by baryonic acoustic oscillations (BAO). The goal would be to obtain a high enough density of sources to probe the three-dimensional density field on the scale of the BAO feature. A percent-level measurement in this redshift range can almost double the Dark Energy Task Force figure of merit, relative to the case with only a similar precision measurement at z{approx}1, if the Universe is not assumedmore »« less

SDSS-III: MASSIVE SPECTROSCOPIC SURVEYS OF THE DISTANT UNIVERSE, THE MILKY WAY, AND EXTRA-SOLAR PLANETARY SYSTEMS

Journal Article Eisenstein, Daniel J. ; Weinberg, David H. ; Agol, Eric ; ... - Astronomical Journal (New York, N.Y. Online)

Building on the legacy of the Sloan Digital Sky Survey (SDSS-I and II), SDSS-III is a program of four spectroscopic surveys on three scientific themes: dark energy and cosmological parameters, the history and structure of the Milky Way, and the population of giant planets around other stars. In keeping with SDSS tradition, SDSS-III will provide regular public releases of all its data, beginning with SDSS Data Release 8 (DR8), which was made public in 2011 January and includes SDSS-I and SDSS-II images and spectra reprocessed with the latest pipelines and calibrations produced for the SDSS-III investigations. This paper presents anmore »« less

Measurement of baryon acoustic oscillations in the Lyman-α forest fluctuations in BOSS data release 9

Journal Article Slosar, Anže ; Iršič, Vid ; Kirkby, David ; ... - Journal of Cosmology and Astroparticle Physics

We use the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 9 (DR9) to detect and measure the position of the Baryonic Acoustic Oscillation (BAO) feature in the three-dimensional correlation function in the Lyman-α flux fluctuations at a redshift z{sub eff} = 2.4. The feature is clearly detected at significance between 3 and 5 sigma (depending on the broadband model and method of error covariance matrix estimation) and is consistent with predictions of the standard ΛCDM model. We assess the biases in our method, stability of the error covariance matrix and possible systematic effects. We fit the resulting correlation function withmore »« less

A 3% DETERMINATION OF H {sub 0} AT INTERMEDIATE REDSHIFTS

Journal Article Lima, J. A. S. ; Cunha, J. V., E-mail: limajas@astro.iag.usp.br, E-mail: jvcunha@ufpa.br - Astrophysical Journal Letters

Recent determinations of the Hubble constant, H {sub 0}, at extremely low and very high redshifts based on the cosmic distance ladder (grounded with trigonometric parallaxes) and a cosmological model (applied to Planck 2013 data), respectively, are revealing an intriguing discrepancy (nearly 9% or 2.4σ) that is challenging astronomers and theoretical cosmologists. In order to shed some light on this problem, here we discuss a new determination of H {sub 0} at intermediate redshifts (z ∼ 1), using the following four cosmic probes: (1) measurements of the angular diameter distances for galaxy clusters based on the combination of the Sunyaev-Zeldovichmore »« less

SDSS-III: Massive Spectroscopic Surveys of the Distant Universe, the Milky Way Galaxy, and Extra-Solar Planetary Systems

Journal Article Eisenstein, Daniel J. ; /Arizona U., Astron. Dept. - Steward Observ. /Harvard U., Phys. Dept. ; Weinberg, David H. ; ... - Submitted to Astron.J.

Building on the legacy of the Sloan Digital Sky Survey (SDSS-I and II), SDSS-III is a program of four spectroscopic surveys on three scientific themes: dark energy and cosmological parameters, the history and structure of the Milky Way, and the population of giant planets around other stars. The Baryon Oscillation Spectroscopic Survey (BOSS) will measure redshifts of 1.5 million massive galaxies and Ly{alpha} forest spectra of 150,000 quasars, using the baryon acoustic oscillation (BAO) feature of large scale structure to obtain percent-level determinations of the distance scale and Hubble expansion rate at z < 0.7 and at z {approx} 2.5.more »« less
