Abstract

In this paper I examine how well Ryskin’s model of emergent cosmic acceleration fits several sets of cosmological observations. I find that while Ryskin’s model is somewhat compatible with the standard model of cosmological acceleration (ΛCDM) for low redshift (z ≲ 1) measurements, its predictions diverge considerably from those of the standard model for measurements made at high redshift (for which z ≳ 1), and it is therefore not a compelling substitute for the standard model.

Probing non-standard gravity with the growth index: a background independent analysis

Journal Article Steigerwald, Heinrich ; Marinoni, Christian ; Bel, Julien, E-mail: heinrich.steigerwald@cpt.univ-mrs.fr, E-mail: jbel@cpt.univ-mrs.fr, E-mail: christian.marinoni@cpt.univ-mrs.fr - Journal of Cosmology and Astroparticle Physics

Measurements of the growth index of linear matter density fluctuations γ(z) provide a clue as to whether Einstein's field equations encompass gravity also on large cosmic scales, those where the expansion of the universe accelerates. We show that the information encoded in this function can be satisfactorily parameterized using a small set of coefficients γ{sub i}, in such a way that the true scaling of the growth index is recovered to better than 1% in most dark energy and dark gravity models. We find that the likelihood of current data, given this formalism and the Λ Cold Dark Matter (ΛCDM)more »« less

Planck 2015 results: XIII. Cosmological parameters

Journal Article Ade, P. A. R. ; Aghanim, N. ; Arnaud, M. ; ... - Astronomy and Astrophysics

Here, this paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. The temperature and polarization power spectra are consistent with the standard spatially-flat 6-parameter ΛCDM cosmology with a power-law spectrum of adiabatic scalar perturbations (denoted “base ΛCDM” in this paper). From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H ₀ = (67.8 ± 0.9) km s ^-1Mpc ^-1, a matter density parameter Ω _m = 0.308 ± 0.012, and a tilted scalar spectral index with n _s = 0.968 ± 0.006, consistent with the 2013 analysis. Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. Combined with the Planck temperature and lensing data, these measurements give a reionization optical depth of τ = 0.066 ± 0.016, corresponding to a reionization redshift of z _re= 8.8more »« less

First study of reionization in tilted flat and untilted non-flat dynamical dark energy inflation models

Journal Article Mitra, Sourav ; Park, Chan-Gyung ; Choudhury, Tirthankar Roy ; ... - Monthly Notices of the Royal Astronomical Society

ABSTRACT We examine the effects of dark energy dynamics and spatial curvature on cosmic reionization by studying reionization in tilted spatially flat and untilted non-flat XCDM and ϕCDM dynamical dark energy inflation models that best fit the Planck 2015 cosmic microwave background (CMB) anisotropy and a large compilation of non-CMB data. We carry out a detailed statistical study, based on a principal component analysis and a Markov chain Monte Carlo analysis of a compilation of lower-redshift reionization data to estimate the uncertainties in the cosmological model reionization histories. We find that, irrespective of the nature of dark energy, there aremore »« less

NINE-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) OBSERVATIONS: FINAL MAPS AND RESULTS

Journal Article Bennett, C. L. ; Larson, D. ; Weiland, J. L. ; ... - Astrophysical Journal, Supplement Series

We present the final nine-year maps and basic results from the Wilkinson Microwave Anisotropy Probe (WMAP) mission. The full nine-year analysis of the time-ordered data provides updated characterizations and calibrations of the experiment. We also provide new nine-year full sky temperature maps that were processed to reduce the asymmetry of the effective beams. Temperature and polarization sky maps are examined to separate cosmic microwave background (CMB) anisotropy from foreground emission, and both types of signals are analyzed in detail. We provide new point source catalogs as well as new diffuse and point source foreground masks. An updated template-removal process ismore »« less

Model-independent limits and constraints on extended theories of gravity from cosmic reconstruction techniques

Journal Article Cruz-Dombriz, Álvaro de la ; Dunsby, Peter K.S. ; Luongo, Orlando ; ... - Journal of Cosmology and Astroparticle Physics

The onset of dark energy domination depends on the particular gravitational theory driving the cosmic evolution. Model independent techniques are crucial to test the both the present ΛCDM cosmological paradigm and alternative theories, making the least possible number of assumptions about the Universe. In this paper we investigate whether cosmography is able to distinguish between different gravitational theories, by determining bounds on model parameters for three different extensions of General Relativity, namely quintessence, F (Τ) and f ( R ) gravitational theories. We expand each class of theories in powers of redshift z around the present time, making no additionalmore »« less
