BICEP and the Keck Array aim to measure the polarization of the cosmic microwave background to find signals from primordial gravitational waves.
Notes on verification
Confirmed by multiple independent, high-quality sources including arXiv papers, a university physics department article, and a Stanford dissertation, all consistent with the claim's description of BICEP/Keck's scientific goals.
