In this paper we emphasize the importance of the Sloan Digital Sky Survey (SDSS) quasi-stellar object (QSO) clustering statistics as a unique probe of the Universe. Because the complete SDSS QSO sample covers a quarter of the observable Universe, cosmological parameters estimated from the clustering statistics have an implication as a test of the cosmological principle, by comparing with those from local galaxies and other cosmological observations. Using an analytical approach to the power… Expand

Optimal Weighting Scheme in Redshift-Space Power Spectrum Analysis and a Prospect for Measuring the Cosmic Equation of State
We develop a useful formula for power spectrum analysis for high- and intermediate-redshift galaxy samples, as an extension of the work by Feldman, Kaiser & Peacock. An optimal weight factor, whichExpand
POWER SPECTRUM ANALYSIS OF THE TWO-DEGREE FIELD QSO SAMPLE REVISITED
We revisit the power spectrum analysis of the complete sample of the Two-Degree field (2dF) QSO redshift (2QZ) survey, as a complementary test of the work by Outram et al. A power spectrum consistentExpand
ON THE FRIEDMANN COSMOLOGY
We derive a functional relation between redshift and light intensity assuming an underlying Friedmann-Robertson-Walker metric without invoking the effects of dark matter and dark energy. OurExpand
Relativistic Dynamics in a Matter-Dominated Friedmann Universe
The energy density of the universe is estimated to be composed of 68% dark energy. Dark energy is associated with the accelerated expansion of the universe. In this work, we consider the evolution ofExpand
A general test of the Copernican principle.
TLDR
This work presents an observational test for the Copernican assumption which can be automatically implemented while the authors search for dark energy in the coming decade, and is entirely independent of any model fordark energy or theory of gravity. Expand

Cosmological constraint from the 2dF QSO spatial power spectrum
We obtain constraints on the cosmological density parameters, Ω m and Ω b , by comparing the preliminary measurement of the quasi-stellar object (QSO) power spectrum from the Two-Degree Field (2dF)Expand
Probing the dark energy with quasar clustering.
TLDR
The Alcock-Paczyński test, as applied to quasar clustering, is a powerful tool to probe the cosmological density and equation of state parameters Omega(m0), Omega(x0), and w and is competitive with future supernova and galaxy number count tests, besides being complementary to them. Expand
Quasar Clustering and Spacetime Geometry
The non-Euclidean geometry of spacetime induces an anisotropy in the apparent correlation function of high-redshift objects, such as quasars, if redshifts and angles are converted to distances inExpand
Observational tests of FRW world models
Observational tests for the cosmological principle are reviewed. Assuming the FRW metric we then summarize estimates of cosmological parameters from various datasets, in particular the cosmicExpand

We examine observational consequences of the cosmological light-cone effect on the power spectrum of the distribution of galaxies and quasars from upcoming redshift surveys. First we derive anExpand
Cosmological Parameters from Redshift-Space Correlations
We estimate how clustering in large-scale redshift surveys can constrain various cosmological parameters. Depth and sky coverage of modern redshift surveys are greater than ever, opening newExpand

We propose cosmological redshift-space distortion of correlation functions of galaxies and quasars as a probe of both the density parameter Ω0 and the cosmological constant λ0. In particular, we showExpand

The feasibility of the geometric test as a probe of the cosmic equation of state of the dark energy is discussed assuming the future Two Degree Field QSO sample. We examine the sensitivity of the QSOExpand

Cosmological-parameter determination with microwave background maps.
TLDR
This work uses a covariance-matrix approach to estimate the precision with which cosmological parameters can be determined by a CMB temperature map as a function of the fraction of sky mapped, the level of pixel noise, and the angular resolution. Expand
