3 K The Cosmic Microwave Background Radiation
1995What processes fixed the designs etched on the cosmic background radiation (CBR)? And what can they tell us about the early Universe, and the origin and evolution of cosmic structure? This review covers all aspects of three decades of study of this ghostly remnant of the hot Big Bang origin of the Universe, and examines the consequences for ...

Cosmic Microwave Background Radiation
Reviews of Modern Physics, 1999Most 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 anisotropy of the cosmic microwave background radiation (CMBR) provide strong evidence supporting this picture. Today, the spectrum of the CMBR matches that of a 2.

Dark Energy and the Cosmic Microwave Background Radiation [PDF]
Physical Review Letters, 2000 We find that current cosmic microwave background anisotropy data strongly constrain the mean spatial curvature of the Universe to be near zero, or, equivalently, the total energy density to be near critical-as predicted by inflation. This result is robust to editing of data sets, and variation of other cosmological parameters (totaling seven, including

Polarization of the cosmic microwave background radiation
Pramana, 1999In re-ionized models, the measurement of polarization of CMBR can be a good criterion to narrow down the parameter space for cosmological models. A Vishniac-type effect in second order polarization over arc minute scales has been calculated. It has been shown that while the effect is very small (∼10−2 µK) for CDM models, it can be ...

STOCHASTIC STABILIZATION OF THE COSMIC MICROWAVE BACKGROUND RADIATION
The Tenth Marcel Grossmann Meeting, 2006Photon trajectories in models of the Universe that have constant negative spatial curvature are exponientially unstable. We demonstrate that they can be stabilized by additional randomm fluctuations in the curvature. The mechanism is analogous to the one responsible for stabilizing the stochastic Kapitza pendulum, We discuss the consequences for the ...

Discovering Relic Gravitational Waves in Cosmic Microwave Background Radiation
, 2007The authority of J.A. Wheeler in many areas of gravitational physics is immense, and there is a connection with the study of relic gravitational waves as well. I begin with a brief description of Wheeler’s influence on this study.

Interpretation of observed cosmic microwave background radiation
Nature, 1977It is argued that the 'surface of last scattering' of the observed microwave background radiation corresponds to the distribution of dust in galaxies or protogalaxies with a temperature of about 110 K at the epoch corresponding to Z roughly equal to 40.

The cosmic microwave background radiation and cosmology
Classical and Quantum Gravity, 1994I review recent observational results on the fundamental properties of the cosmic microwave-background radiation, with special emphasis on the findings of the COBE satellite. These include the present temperature of the radiation, , and the first convincing detection of angular variations in its intensity, at a level on scales .

Cosmic Microwave Background Radiation Constraints on a Modified Chaplygin Gas Model
, 2005A modified Chaplygin gas model of unifying dark energy and dark matter with the exotic equation of state p = Bρ−(A/ρα), which can also explain the recent expansion of the universe, is investigated by means of constraining the location of the peak of the ...
