Bennett and colleagues: first-year WMAP maps and basic results

What changed

Reported WMAP’s first-year full-sky microwave maps in five frequency bands, separated foreground emission and characterized calibration, anisotropy statistics and basic cosmological results.

Scientific scope

The record is the exact 2003 Astrophysical Journal Supplement article with its twenty-one-author byline. Other first-year WMAP analysis papers, later data releases, parameter fits and Planck results remain separate.
