TL;DR: In this article, a cosmological constraint from observations with the BICEP2 and Keck Array experiments up to and including the 2015 observing season (BK15) was presented, resulting in the deepest CMB polarization maps to date and a statistical sensitivity to the tensor-to-scalar ratio of $\sigma(r) = 0.0027 \pm 0.020$.
