The Cosmic Microwave Background [PDF]
Living Reviews in Relativity, 1998 We present a brief review of current theory and observations of the cosmic microwave background (CMB). New predictions for cosmological defect theories and an overview of the inflationary theory are discussed.

New physics from the polarized light of the cosmic microwave background [PDF]
Nature Reviews Physics, 2022 The current cosmological model requires new physics beyond the standard model of elementary particles and fields, such as dark matter and dark energy. Their nature is unknown and so is that of the initial fluctuations in the early Universe that led to ...

Uncovering the history of cosmic inflation from anomalies in cosmic microwave background spectra [PDF]
European Physical Journal C: Particles and Fields, 2022 We propose an inflationary primordial feature model that can explain both the large and small-scale anomalies in the currently measured cosmic microwave background anisotropy spectra, revealing a clip of adventurous history of the Universe during its ...

Cosmic Microwave Background Polarization
Journal of Physics: Conference Series, 2005 Cosmic microwave background (CMB) anisotropy is our richest source of cosmological information; the standard cosmological model was largely established thanks to study of the temperature anisotropies.

Comparing Cosmic Microwave Background Datasets [PDF]
Physical Review D, 1998 To extract reliable cosmic parameters from cosmic microwave background datasets, it is essential to show that the data are not contaminated by residual non-cosmological signals. We describe general statistical approaches to this problem, with an emphasis

Cosmic microwave background theory. [PDF]
Proc Natl Acad Sci U S A, 1998 A long-standing goal of theorists has been to constrain cosmological parameters that define the structure formation theory from cosmic microwave background (CMB) anisotropy experiments and large-scale structure (LSS) observations. The status and future promise of this enterprise is described.

The Temperature of the Cosmic Microwave Background [PDF]
, 2009 The FIRAS data are independently recalibrated using the WMAP data to obtain a CMB temperature of 2.7260 +/- 0.0013. Measurements of the temperature of the cosmic microwave background are reviewed.
