Observations of the Isotropy of the Cosmic Microwave Background Radiation
Annual Review of Astronomy and Astrophysics, 1992Over the past decade the anisotropy of the microwave background radiation has emerged as a field of fundamental importance to astrophysics due to its significance in theories of galaxy formation and in the quest for the physical origin of fluctuations. The history of the development of this subject may be divided into three phases. In the first phase,

Measurement of Cosmic Microwave Background Radiation
IEEE Transactions on Microwave Theory and Techniques, 1968The techniques associated with the measurement of antenna temperature at microwave frequencies are discussed. A number of experiments designed to measure cosmic microwave background radiation are described and their results compared. These results give a very good fit to a 3/spl deg/K black body curve between 1.4 and 35 GHz.

The dipole anisotropy of the cosmic microwave background radiation
New Astronomy Reviews, 2002Abstract We review the prediction, discovery and precise measurements of CMB Dipole Anisotropy, a field in which Dennis Sciama has provided important initial insight.

History of the Discovery of the Cosmic Microwave Background Radiation [PDF]
Radio astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery

Ripples in the Cosmic Microwave Background Radiation
2016The Cosmic Microwave Background Explorer satellite (COBE) of NASA, launched in 1989, measured with unprecedented precision the intensity of the cosmic microwave background radiation (CMB) at many wavelengths and in all directions over the sky. The spatial resolution (sharpness) of the microwave optics in the satellite was 7°—14 times the diameter of ...

Precision of slow-roll predictions for the cosmic microwave background radiation anisotropies
, 1999Inflationary predictions for the anisotropy of the cosmic microwave background radiation are often based on the slow-roll approximation. We study the precision with which the multipole moments of the temperature two-point correlation function can be ...

Fluctuations in Cosmic Microwave Background Radiation
2013Cosmic microwave background (CMB) radiation is composed of photons which have decoupled from electrons in the epoch of the hydrogen and helium recombination at \(z = 1{,}089\) and it is observed as the perfectly black body radiation whose averaged temperature is 2.725 K. More precisely, however, the CMB involves tiny spatial fluctuations. Theoretically,

Fluctuations in the Cosmic Microwave Background Radiation
1998The 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 structure of the Universe with observation. The problem addressed in this chapter is how to relate the fluctuations in the dark and baryonic matter on the ...

Quantum effects in the cosmic microwave background radiation
Physics Letters A, 1990Abstract Based on the quantum correlated general relativistic Vlasov equations in an Einstein-de Sitter universe, we show that quantum effects are beyond measurability in the cosmic microwave background radiation.
