Two CMB Signals Timed Reionization
A forecast combines kinematic Sunyaev-Zel'dovich power with CMB lensing to constrain the era's midpoint and duration.
Summary
A forecast combines kinematic Sunyaev-Zel'dovich power with CMB lensing to constrain the era's midpoint and duration.
Simulation forecasts find the cross-information sensitive to both the midpoint and duration of reionization. The authors estimate signal-to-noise of roughly two to three for a Simons-Observatory-like experiment and about 50 for a CMB-HD-like survey; these are forecasts, not present detections.
Why it matters
