WMAP Data Product Images

Figures from the Five-Year WMAP papers in a form suitable for use in talks.

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.

Temperature and polarization power spectra derived from the WMAP 5-year data. Data are represented as points, curves correspond to the best-fit LCDM model, and shaded regions delineate cosmic variance about the model.

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.

Three-color maps from the Maximum Entropy Method (MEM) model for the 5 WMAP frequency bands. These maps indicate which emission mechanism dominates as a function of frequency and sky position. Synchrotron is red, free-free is green, and thermal dust is blue.
