简介
Determining the origin of structure in the universe is one of the most important open problems in cosmology. CMB anisotropies sourced by early-universe density perturbations are currently the most powerful observational probe of the earliest mechanisms of structure formation. It is possible that the same processes that produced the density perturbations also sourced tensor perturbations, or primordial gravitational waves (PGWs). If this is the case, detecting a PGW signal would yield insight into physics far earlier than the epoch of recombination, and allow us to build an unprecedented understanding of the earliest moments of time.
PGWs leave imprints on the polarization of the CMB (Hu & White 1997; Kamionkowski et al. 1997; Seljak & Zaldarriaga 1997). In particular, the sensitivity of CMB measurements to gravitational waves arises from the generation of polarization at the surface of last scattering: to first order …
