Forecasts of CMB $E$-mode anomalies for AliCPT-1

Jiazheng Dou, Wen Zhao

Forecasts indicate AliCPT combined with Simons Observatory can detect injected E-mode dipole modulation at 99% confidence, while AliCPT alone risks biases in alignment and parity tests due to limited sky coverage.

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

For dipole modulation, we validate the local variance estimator on modulated simulations with an input amplitude A_d = 0.07, and find that the combined AliCPT+SO dataset is likely to detect the injected E-mode modulation at a 99% confidence level.

C2weakest assumption

That the NILC component separation applied to the simulated maps perfectly isolates the E-mode signal without introducing biases that mimic or mask the anomalies, and that the statistical properties of any real E-mode anomalies match those assumed in the unconstrained isotropic simulations.
