TL;DR: In this paper, the authors present three-year full-sky maps of the polarization and analyze them for foreground emission and cosmological implications and find that the limit from the polarization signals alone is r<2.2 (95% CL) corresponding to a limit on the cosmic density of gravitational waves of Omega{GW}h^2 < 5 times 10−12.

TL;DR: The detection of an extremely intense radio burst from the Galactic magnetar SGR 1935+2154 using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project implies a burst energy at 400 to 800 megahertz of approximately 3 × 1034 erg, which is three orders of magnitude higher than the burst energy of any radio-emitting magnetar detected thus far.

TL;DR: The Millimeter Bolometer Array Camera (MBAC) as discussed by the authors was installed on the 6-meter Atacama Cosmology Telescope (ACT) in late 2007, where it was used for the first season of observations, comprising a 145 GHz diffraction-limited, 1024-pixel, focal plane array of Transition Edge Sensor (TES) Bolometers.

TL;DR: The BICEP2 and the Keck Array are part of a program of experiments at the South Pole whose main goal is to achieve the sensitivity and systematic control necessary for measurements of the tensor-to-scalar ratio at σ(r) ~ 0:01 as discussed by the authors.
