TL;DR: An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.

TL;DR: Strong evidence for dust and no statistically significant evidence for tensor modes is found and various model variations and extensions are probe, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint.

TL;DR: The BICEP2 telescope as discussed by the authors measured the polarization of the cosmic microwave background (CMB) on angular scales of 1°-5° (l = 40-200), near the expected peak of the B-mode polarization signature of primordial gravitational waves from cosmic inflation.
