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 of the microwave background reflect the conditions that prevailed in the early Universe. Analysis of the physical mechanisms by which these anisotropies formed shows how they may be used to constrain fundamental cosmological parameters and provide insight into the origin of large-scale structure in the… 
The Cosmic microwave background radiation
Cosmic Microwave Background
The standard hot big bang model predicts that today the universe has a temperature of a few Kelvin [1]. In 1964, a background signal was discovered and found consistent with a black-body spectrum at
Cosmic Microwave Background Radiation
Most astronomers and physicists now believe that we live in an expanding universe that evolved from an early state of extremely high density and temperature. Measurements of the spectrum and
Fluctuations in the Cosmic Microwave Background
The Cosmic Microwave Background (CMB) gives us a snapshot of the universe when it was hotter, denser and simpler than today. It is relic radiation from the Big Bang, left over from the transition
Fluctuations in the Cosmic Microwave Background Radiation
The study of the power-spectrum of spatial fluctuations in the Cosmic Microwave Background Radiation provides one of the most important means of confronting theories of the origin of the large-scale
Calculation of Cosmic Background Radiation Anisotropies and Implications
We review the physical processes that are thought to produce anisotropy in the cosmic microwave background, focusing primarily (but not exclusively) on the effects of acoustic waves in the early
Determination of Cosmological Parameters from Cosmic Microwave Background Anisotropies
New cosmic microwave background anisotropies data are increasingly improving our understanding of the evolution and formation of structures in the universe. Here we briefly discuss the cosmological
The Cosmic Microwave Background
TLDR
Current CMB data is used to set some preliminary constraints on the values of fundamental cosmological parameters Ω and Ho using the maximum likelihood technique and secondary anisotropies due to the Sunyaev-Zel’dovich effect are described.
Multiple Peaks in the CMB
Recent measurements of the Cosmic Microwave Background Anisotropy have provided evidence for the presence of oscillations in the angular power spectrum. These oscillations are a wonderful
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.

Perturbations of the Cosmic Microwave Background Radiation and Structure Formations
After the recent discovery of temperature fluctuations of the cosmic microwave background radiation by COBS, the study of the temperature fluctuations becomes more and more important for
Measuring cosmological parameters with cosmic microwave background experiments.
TLDR
The degree to which factors related to primordial energy density and gravitational wave fluctuations can be separately resolved from combined small- and large-angular-scale anisotropy observations is examined.
From Microwave Anisotropies to Cosmology
TLDR
Analysis of all of the published detections suggests the existence of a peak on degree scales with a height 2.4 to 10 times the amplitude of the power spectrum at large angular scales, which implies that the universe did in fact recombine, and limits theories of structure formation.
Imprint of Omega on the cosmic microwave background.
We investigate the dependence of large angular scale cosmic microwave background anisotropies on various initial conditions, including both adiabatic and isocurvature perturbations and the initial
Doppler peaks from cosmic texture.
TLDR
The angular power spectrum of temperature anisotropies on the microwave sky in the cosmic texture theory shows `Doppler' peaks analogous to those in scenarios based on primordial adiabatic fluctuations such as `standard CDM', but at quite different angular scales.
Fine-scale anisotropy of the cosmic microwave background in a universe dominated by cold dark matter
The fine-scale anisotropy of the cosmic microwave background radiation has been studied in cosmological models with a scale-invariant primordial adiabatic density fluctuation spectrum that are
Cosmic background radiation anisotropies in universes dominated by nonbaryonic dark matter
Detailed calculations of the temperature fluctuations in the cosmic background radiation for universes dominated by massive collisionless relics of the big bang are presented. An initially adiabatic
Acoustic Signatures in the Cosmic Microwave Background
We study the uniqueness and robustness of acoustic signatures in the cosmic microwave background by allowing for the possibility that they are generated by some as yet unknown source of gravitational
The imprint of proper motion of nonlinear structures on the cosmic microwave background
We investigate the imprint of nonlinear matter condensations on the cosmic microwave background (CMB) in an Omega = 1, cold dark matter (CDM) model universe. Temperature anisotropies are obtained by
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.
