Polarized Anisotropic Stochastic Gravitational Wave Background Search with Ground-Based Detector Networks
feeds.aps.org · By Töre Boybeyi & Vuk Mandic ·
The Brief
- Töre Boybeyi and Vuk Mandic present a search for polarized anisotropic stochastic gravitational wave background using ground-based detector networks.
- The work states that gravitational waves admit a Stokes decomposition into intensity (I), circular polarization (V), and linear polarization (Q, U), analogous to CMB polarimetry.
- The authors implement a full-Stokes maximum-likelihood approach; the available excerpt is truncated and reports no results.
Why it matters
It extends searches for anisotropic gravitational wave backgrounds to full Stokes polarization, offering a method to characterize the polarization of the background with existing detector networks.
