 Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Final Maps and Results by C. L. Bennett and others

The December 20, 2012 preprint was available before the January 2013 examination. Its abstract reports combined cosmic microwave background, baryon acoustic oscillation and Hubble-constant model fits, including spatial curvature and cosmic age. These combined-data constraints should not be attributed to the cosmic microwave background alone.
