CMB B-mode polarization

Curl-like polarization patterns in the cosmic microwave background. Gravitational lensing produces some of them; a primordial component would be evidence of gravitational waves from the early universe.

UC San Diego's cross-check reproduces the standard calibration pattern across eight Planck maps

UC San Diego physicists cross-checked eight Planck polarization maps and found their relative calibration matches the standard analysis. The test cancels any rotation all detectors share, so the hinted 0.37-degree twist still needs an absolute angle reference.
