Description
Some inflationary models predict a circularly polarized stochastic gravitational-wave background (SGWB) with potential cosmological significance. We develop a simulation and parameter-estimation framework to characterize circular polarization and Doppler-induced dipole anisotropies in the SGWB. The pipeline jointly constrains the polarization degree (Π), energy density (Ω_GW), and dipole amplitude (D_α), validated through simulated signals and applied to LIGO O1–O3 data. We derive upper limits on Π, Ω_GW, and D_α.
