Description

The expanding catalog of gravitational wave detections enables novel tests of General Relativity, including probes of waveform polarization content. Many polarization studies rely on null stream methods, neglecting the known non-stationary and non-Gaussian features of detector noise. Using simulations, we quantify how this noise idealization affects inferences of non‑tensorial polarization modes and characterize the resulting bias in null stream polarization tests.
