TL;DR: In this paper, the authors presented the strongest constraints to date on anisotropies of cosmic microwave background (CMB) polarization rotation derived from 150 GHz data taken by the BICEP2 & Keck Array CMB experiments up to and including the 2014 observing season (BK14).

TL;DR: BICEP3 as mentioned in this paper is a 550 mm-aperture refracting telescope for polarimetry of radiation in the cosmic microwave background at 95 GHz, which adopts the methodology of BICEP2 and the Keck Array experiments - it possesses sufficient resolution to search for signatures of the inflation-induced cosmic gravitational wave background while utilizing a compact design for ease of construction and to facilitate the characterization and mitigation of systematics.
