Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Galactic Foreground Emission
B. Gold, C. L. Bennett, R. S. Hill +15
We present a new estimate of foreground emission in the WMAP data, using a Markov chain Monte Carlo (MCMC) method. The new technique delivers maps of each foreground component for…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Angular Power Spectra
M. R. Nolta, J. Dunkley, R. S. Hill +17
We present the temperature and polarization angular power spectra of the cosmic microwave background (CMB) derived from the first 5 years of WMAP data. The 5-year temperature (TT)…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Likelihoods and Parameters from the WMAP data
J. Dunkley, E. Komatsu, M. R. Nolta +16
This paper focuses on cosmological constraints derived from analysis of WMAP data alone. A simple LCDM cosmological model fits the five-year WMAP temperature and polarization data.…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP)Observations: Beam Maps and Window Functions
R. S. Hill, J. L. Weiland, N. Odegard +15
Cosmology and other scientific results from the WMAP mission require an accurate knowledge of the beam patterns in flight. While the degree of beam knowledge for the WMAP one-year…
Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles, Data Processing, Radiometer Characterization and Systematic Error Limits
N. Jarosik, C. Barnes, M. R. Greason +18
The WMAP satellite has completed 3 years of observations of the cosmic microwave background radiation. The 3-year data products include several sets of full sky maps of the Stokes…
Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Temperature Analysis
G. Hinshaw, M. R. Nolta, C. L. Bennett +19
We present new full-sky temperature maps in five frequency bands from 23 to 94 GHz, based on the first three years of the WMAP sky survey. The new maps, which are consistent with t…
Three Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Polarization Analysis
L. Page, G. Hinshaw, E. Komatsu +20
The Wilkinson Microwave Anisotropy Probe WMAP has mapped the entire sky in five frequency bands between 23 and 94 GHz with polarization sensitive radiometers. We present three-year…
Wilkinson Microwave Anisotropy Probe (WMAP) Three Year Results: Implications for Cosmology
D. N. Spergel, R. Bean, O. Doré +19
A simple cosmological model with only six parameters (matter density, Omega_m h^2, baryon density, Omega_b h^2, Hubble Constant, H_0, amplitude of fluctuations, sigma_8, optical de…
Measurement of Cosmic Shear with the Space Telescope Imaging Spectrograph
Jason Rhodes, Alexandre Refregier, Nicholas R. Collins +3
Weak lensing by large-scale structure allows a direct measure of the dark matter distribution. We have used parallel images taken with the Space Telescope Imaging Spectrograph (STI…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Angular Power Spectrum
G. Hinshaw, D. N. Spergel, L. Verde +14
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…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Galactic Signal Contamination from Sidelobe Pickup
C. Barnes, R. S. Hill, G. Hinshaw +10
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 p…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Preliminary Maps and Basic Results
C. L. Bennett, M. Halpern, G. Hinshaw +18
We present full sky microwave maps in five bands (23 to 94 GHz) from the WMAP first year sky survey. Calibration errors are <0.5% and the low systematic error level is well specifi…
