Interpretation of observed cosmic microwave background radiation

Nature, 1978
The Alfven and Mendis (1977) conclusion that dust grains in galaxies render the universe opaque to cosmic microwave background at a red shift ratio equal to 40 is challenged by a calculation of the opacity of galactic dust grains to the microwave background radiation from the time of decoupling at emission red shift ratio equal to 1500 to the present ...

Statistics of Cosmic Microwave Background Radiation with the Cosmic String Model

International Journal of Modern Physics D, 1997
We have studied the cosmic microwave background radiation by simulating the cosmic string network induced anisotropies on the sky. The large-angular size simulations are based on the Kaiser–Stebbins effect calculated from full cosmic-string network simulation.

Neutrino physics with the cosmic microwave background radiation

Nuclear Physics B - Proceedings Supplements, 2000
Abstract The fluctuations in the Cosmic Microwave Background Radiation (CMBR) contain key information about the physical conditions in the early universe. Two new satellites are expected to measure the CMBR fluctuation spectrum so precisely that almost all the relevant cosmological parameters can be determined at the percent level. This is great news

Measuring the Cosmic Microwave Background Radiation (CMBR) polarization with QUIET

, 2008
A major goal of upcoming experiments measuring the Cosmic Microwave Background Radiation (CMBR) is to reveal the subtle signature of inflation in the polarization pattern which requires unprecedented sensitivity and control of systematics.

Interpretation of the cosmic microwave background radiation anisotropy detected by the COBE Differential Microwave Radiometer

, 1992
The large-scale cosmic background anisotropy detected by the COBE Differential Microwave Radiometer (DMR) instrument is compared to the sensitive previous measurements on various angular scales, and to the predictions of a wide variety of models of ...

Chemical anisotropy of the cosmic microwave background radiation

Astronomische Nachrichten, 2020
AbstractIt is shown how the large‐scale inhomogeneous distribution of chemical elements in the primordial medium contributes to temperature fluctuations of the cosmic microwave background radiation (CMB). The magnitude of the chemical anisotropy of the CMB, which is sensitive to the absolute and relative abundance of chemical elements at the time of ...

The cosmic microwave background radiation and galaxy formation

Canadian Journal of Physics, 1986
Observational limits on the microwave-background-radiation anisotropy on various angular scales are reviewed. Comparison is made with the predictions of the gravitational-instability theory of galaxy formation from primordial fluctuations in the very early universe.

Topology of the Universe and the Cosmic Microwave Background Radiation

2003
Recent astronomical observations of recession of further and further galaxies and clusters of galaxies, estimates of masses of clusters of galaxies, studies of temperature anisotropics of cosmic microwave background radiation, and type Ia supernovae suggest that the universe is flat (Euclidean).

Cosmic Microwave Background Radiation Anisotropies in Brane Worlds

Physical Review Letters, 2003
We propose a new formulation to calculate the cosmic microwave background (CMB) spectrum in the Randall-Sundrum two-brane model based on recent progress in solving the bulk geometry using a low energy approximation. The evolution of the anisotropic stress imprinted on the brane by the 5D Weyl tensor is calculated.
