Atacama Cosmology Telescope - Results

Results

ACT released results measuring the statistical properties of the temperature of the CMB down to arcminute scales in January 2010. It found signals that were consistent with un-resolved point sources and the SZ effect. In 2011, ACT made the first detection of the power spectrum of gravitational lensing of the microwave background, which, combined with the WMAP results, has for the first time provided evidence for dark energy from the CMB alone. Measurements of the CMB power spectrum from the South Pole Telescope were subsequently released that were later also shown to provide evidence for dark energy from the CMB alone.

Famous quotes containing the word results:

    “The study and knowledge of the universe would somehow be lame and defective were no practical results to follow.”
    —Marcus Tullius Cicero (106–43 B.C.)

    “We do not raise our children alone.... Our children are also raised by every peer, institution, and family with which they come in contact. Yet parents today expect to be blamed for whatever results occur with their children, and they expect to do their parenting alone.”
    —Richard Louv (20th century)

    “Social improvement is attained more readily by a concern with the quality of results than with the purity of motives.”
