The Cosmic Microwave Background (CMB) is a relict of the early universe. Its perfect 2.725K blackbody spectrum demonstrates that the universe underwent a hot, ionized early phase; its anisotropy (about 80 µK rms) provides strong evidence for the presence of photon-matter oscillations in the primeval plasma, shaping the initial phase of the formation of structures; its polarization state (about 3 µK rms), and in particular its rotational component (less than 0.1 µK rms) might allow to study the…

Detection of polarization in the cosmic microwave background using DASI
TLDR
The detection of polarization of the CMB with the Degree Angular Scale Interferometer (DASI) is reported, and its level and spatial distribution are in excellent agreement with the predictions of the standard theory.
Linear polarized fluctuations in the cosmic microwave background
It has been recognized since the early work of Silk1 and Sachs and Wolfe2 that inhomogeneities in density, velocity fields or gravitational potential can produce small amplitude fluctuations in the
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.
CMB observations and the production of chemical elements at the end of the dark ages
The metallicity evolution and ionization history of the universe must leave its imprint on the Cosmic Microwave Background through resonant scattering of CMB photons by atoms, ions and molecules.
Planck early results. III. First assessment of the Low Frequency
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six wide bands centered
Bolometric Detectors for Measurements of the Cosmic Microwave Background
Measurements of the Cosmic Microwave Background radiation provide the strongest support for the standard model of Inflationary Big Bang Cosmology. This paper sketches the impact of past and future
The Large-Scale Polarization Explorer (LSPE)
The LSPE is a balloon-borne mission aimed at measuring the polarization of the Cosmic Microwave Background (CMB) at large angular scales, and in particular to constrain the curl component of CMB
The Temperature of the Cosmic Microwave Background at 10 GHz
We report the results of an effort to measure the low-frequency portion of the spectrum of the cosmic microwave background (CMB) radiation, using a balloon-borne instrument called the Absolute
Improved Measurement of the Angular Power Spectrum of Temperature Anisotropy in the Cosmic Microwave Background from Two New Analyses of BOOMERANG Observations
We report the most complete analysis to date of observations of the cosmic microwave background (CMB) obtained during the 1998 flight of BOOMERANG. We use two quite different methods to determine the
Detection of cosmic microwave background anisotropy at 1.8 deg: Theoretical implications on inflationary models
Theoretical scenarios for the formation of large-scale structure in the universe are strongly constrained by ARGO (a balloon borne experiment reporting detection of cosmic microwave background
