[submitted] FRB DM cross Timing: Primordial Non-Gaussianity Fisher Pipeline
This pipeline forecasts constraints on the local primordial non-Gaussianity parameter fNL using the joint angular power spectra of Fast Radio Burst (FRB) Dispersion Measure (DM) and timing delay fields. The key result is that the DM × timing cross-spectrum self-calibrates the electron bias parameter b_e, dramatically improving fNL constraints.
