Description
Thanks to exquisite CMB B-mode data, we should see within the next few years massive improvements in constraints on a background of gravitational waves from inflation. In particular, SPT-3G and BICEP (SPO) have collected now enough data to achieve, in principle, 3 times better constraints on the tensor-to-scalar ratio than currently published, after the delicate removal of their main contaminant, the gravitational lensing signal. I'll discuss the CMB B-mode observational program, and work on these extremely deep maps towards this objective.
