The advent of high signal-to-noise cosmic microwave background (CMB) anisotropy experiments now allow detailed studies on the statistics related to temperature fluctuations. The existence of acoustic oscillations in the anisotropy power spectrum is now established with the clear detection of the first, and to a lesser confidence the second and the third, peak. Beyond the acoustic peak structure associated with CMB photon temperature fluctuations, we study the possibility for an observational… Expand

Non‐linear galaxy power spectrum and cosmological parameters
The galaxy power spectrum is now a well-known tool of precision cosmology. In addition to the overall shape, baryon oscillations and the small-scale suppression of power by massive neutrinos captureExpand

Baryonic signatures in Large-Scale Structure
We investigate the consequences of a non-negligible baryon fraction for models of structure formation in cold dark matter dominated cosmologies, emphasizing in particular the existence ofExpand
Small scale cosmological perturbations: An Analytic approach
Through analytic techniques verified by numerical calculations, we establish general relations between the matter and cosmic microwave background (CMB) power spectra and their dependence onExpand
A High Spatial Resolution Analysis of the MAXIMA-1 Cosmic Microwave Background Anisotropy Data
We extend the analysis of the MAXIMA-1 cosmic microwave background data to smaller angular scales. MAXIMA, a bolometric balloon-borne experiment, mapped a 124 deg2 region of the sky with 10'Expand
A flat Universe from high-resolution maps of the cosmic microwave background radiation
TLDR
The first images of resolved structure in the microwave background anisotropies over a significant part of the sky are reported, consistent with that expected for cold dark matter models in a flat (euclidean) Universe, as favoured by standard inflationary models. Expand
Measuring Angular Diameter Distances through Halo Clustering
Current and upcoming wide-field surveys for weak gravitational lensing and the Sunyaev-Zeldovich effect will generate mass-selected catalogs of dark matter halos with internal or follow-upExpand
Acoustic Oscillations in the Early Universe and Today
TLDR
Comparisons of the CMB detections with the corresponding acoustic oscillations in the matter-density power spectrum provide further support for the standard Hot Big Bang model of the universe. Expand
The 2dF Galaxy Redshift Survey: the power spectrum and the matter content of the Universe
The 2dF Galaxy Redshift Survey has now measured in excess of 160 000 galaxy redshifts. This paper presents the power spectrum of the galaxy distribution, calculated using a direct Fourier transformExpand
Expectations for an Interferometric Sunyaev-Zeldovich Effect Survey for Galaxy Clusters
We estimate the expected yield of a nontargeted survey for galaxy clusters using the Sunyaev-Zeldovich effect (SZE). Estimating survey yields requires a detailed model for both cluster properties andExpand
Discovery of a Galaxy Cluster via Weak Lensing
We report the discovery of a cluster of galaxies via its weak gravitational lensing effect on background galaxies, the first spectroscopically confirmed cluster to be discovered through itsExpand
The physics of microwave background anisotropies
The residual radiation from the Big Bang is observable as the cosmic microwave background–a near-uniform sea of photons with an average temperature of 2.7 K. Small variations in the temperature ofExpand
