Constraining FRB Microstructure with Polarised Shot Noise

A. Bera, B. Meyers, C. W. James, J. C. F. Balzan

A shot-noise model of fast radio bursts as many microshots with random polarizations accounts for observed differences in polarization variability across the burst profile.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

FIRES can reproduce key spectro-polarimetric behaviours seen in these data: scattering suppresses PA variability on the trailing edge, while the leading edge preferentially retains intrinsic structure when sufficient signal-to-noise is present.

C2weakest assumption

That FRB dynamic spectra are well described as the incoherent superposition of Gaussian microshots whose polarization angles are drawn from a distribution whose form and parameters are independent of the emission mechanism.

C3one line summary

FIRES models FRBs as incoherent superpositions of Gaussian microshots with varying polarization angles and uses this to reproduce observed PA variability and linear fraction in two CRAFT bursts while mapping allowed regions of microshot number, PA dispersion, and intrinsic polarization.
