Mather and colleagues: COBE FIRAS measurement of the microwave-background spectrum

What changed

The thermal origin of the microwave background gained stringent spectral confirmation.

Scientific scope

Exact 23-author 1994 spectrum paper; 1990 preliminary spectrum, anisotropy mapping and later full data separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1994 Astrophysical Journal FIRAS spectrum paper. The preliminary 1990 spectrum, COBE anisotropy mapping, instrument construction, later full-data analyses and cosmological interpretation remain separate.
