WMAP Full-sky Temperature Maps
The images below represent full-sky maps of the cosmic microwave background anisotropy and foreground signal from our galaxy (in red). The 5 frequency maps are constructed from the differential time-ordered observations of the ten WMAP differencing assemblies. Galactic foreground is stongest in K band, weakest in V and W bands.

WMAP CMB Power Spectra
Temperature and polarization power spectra derived from the WMAP Seven-year data. Data are represented as points, curves correspond to the best-fit LCDM model, and shaded regions delineate cosmic variance about the model.

WMAP Internal Linear Combination Map
The Internal Linear Combination Map is a weighted linear combination of the five WMAP frequency maps. The weights are computed using criteria which minimize the Galactic foreground contribution to the sky signal. The resultant map provides a low-contamination image of the CMB anisotropy.

WMAP Polarizing Pattern
The standard model predicts a specific linked pattern of temperature and polarization around hot and cold spots in the map. WMAP now sees the predicted pattern in the map, as shown in the figure.

W-Band WMAP Polarizing Pattern
WMAP has produced a visual demonstration that the polarization pattern around hot and cold spots follows the pattern expected in the standard model.
