On Determining the Spectrum of Primordial Inhomogeneity from the COBE DMR Sky Maps: II. Results of Two Year Data Analysis

TLDR
In this article, a new technique of Fourier analysis on a cut sky (Gorski, 1994) has been applied to the two year COBE DMR sky maps.
Abstract
A new technique of Fourier analysis on a cut sky (Gorski, 1994) has been applied to the two year COBE DMR sky maps. The Bayesian power spectrum estimation results are consistent with the Harrison-Zel'dovich n=1 model. The maximum likelihood estimates of the parameters of the power spectrum of primordial perturbations are n=1.22 (1.02) and Q_{rms-PS}=17 (20) uK including (excluding) the quadrupole anisotropy. The marginal likelihood function on n renders n=1.10 \pm 0.32 (0.87 \pm 0.36).

Cosmic strings

TL;DR: Cosmic strings provide a bridge between the physics of the very small and the very large They are predicted by some unified theories of particle interactions If they exist, they may help to explain some of the largest-scale structures seen in the Universe today as mentioned in this paper.

The observational case for a low-density Universe with a non-zero cosmological constant

TL;DR: In this paper, the authors show that there remains a wide range of cosmological models in good concordance with these constraints, and they point to models in which the matter density of the universe falls well below the critical energy density required to halt its expansion.

The density and peculiar velocity fields of nearby galaxies

TL;DR: In this article, the authors review the quantitative science that can be and has been done with redshift and peculiar velocity surveys of galaxies in the nearby universe, and discuss in some detail the various quantitative cosmological tests that can also be carried out with the redshift data.
