An angular power spectrum analysis of the DRAO 1.4 GHz polarization survey: implications for CMB observations
Aims. The aim of the present analysis is to improve the knowledge of the statistical properties of the Galactic diffuse synchrotron emission, which constrains sensitive CMB anisotropy measurements.
The impact of Galactic synchrotron emission on CMB anisotropy measurements. I. Angular power spectru
Context. Galactic foreground emission fluctuations are a limiting factor for precise cosmic microwave background (CMB) anisotropy measurements. Aims. We intend to improve current estimates of the
Foreground Implications in the Scientific Exploitation of CMB Data
The study of the Cosmic Microwave Background (CMB) represents one of the main sources of information on which the modern cosmology is based. The observables characterizing the CMB are: its own photon
What is the B mode in CMB polarization
A linear polarization field on a surface is expressed in terms of scalar functions, providing an invariant separation into two components; one of these is the B mode, important as a signature of
The Synthesis of the Elements and the Formation of Stars
One of the prerequisites for life is the presence of elements such as H, C, O, N, S and P. Those elements, with the exception of hydrogen, the most abundant element in space, were not yet present in
The coexistence of cognitive radio and radio astronomy
The signal levels resulting from cognitive radio systems indicate that spectral bands used for cognitive radio applications cannot be used for radio astronomical research, which would cause loss of operation for passive users of the spectrum.


First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Preliminary maps and basic results
We present full-sky microwave maps in five frequency bands (23-94 GHz) from the Wilkinson Microwave Anisotropy Probe (WMAP) first-year sky survey. Calibration errors are less than 0.5%, and the low
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles and Window Functions
Knowledge of the beam profiles is of critical importance for interpreting data from cosmic microwave background experiments. In this paper, we present the characterization of the in-flight optical
First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: The Angular power spectrum
We present the angular power spectrum derived from the first-year Wilkinson Microwave Anisotropy Probe (WMAP) sky maps. We study a variety of power spectrum estimation methods and data combinations
First-Year Wilkinson Microwave Anisotropy Probe (WMAP)* Observations: Implications For Inflation
We confront predictions of inflationary scenarios with the Wilkinson Microwave Anisotropy Probe (WMAP) data, in combination with complementary small-scale cosmic microwave background (CMB)
First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Data processing methods and systematic errors limits
We describe the calibration and data processing methods used to generate full-sky maps of the cosmic microwave background (CMB) from the first year of Wilkinson Microwave Anisotropy Probe (WMAP)
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Galactic Signal Contamination from Sidelobe Pickup
Since the Galactic center is ~1000 times brighter than fluctuations in the cosmic microwave background (CMB), CMB experiments must carefully account for stray Galactic pickup. We present the level of
The primary goal of the MAP satellite, now in orbit, is to make high-fidelity polarization-sensitive maps of the full sky in five frequency bands between 20 and 100 GHz. From these maps we will
First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Determination of cosmological parameters
WMAP precision data enable accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat � -dominated universe seeded by a nearly scale-invariant adiabatic
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Foreground Emission
The WMAP mission has mapped the full sky to determine the geometry, content, and evolution of the universe. Full sky maps are made in five microwave frequency bands to separate the temperature
Polarization and anisotropy of the microwave sky.
This work studies the polarization-polarization and polarization-temperature correlations in standard adiabatic scenarios for structure formation and calculates the expected signal to noise ratio for various measures of the polarization in a hypothetical mapping experiment.
