Foreground and Sensitivity Analysis for Broadband (2D) 21 cm–Ly<i>α</i>and 21 cm–H<i>α</i>Correlation Experiments Probing the Epoch of Reionization
A detection of the predicted anticorrelation between 21cm and either Ly-alpha or H-alpha from the Epoch of Reionization (EOR) would be a powerful probe of the first galaxies. While 3D intensity maps isolate foregrounds in low k_\parallel modes, infrared surveys cannot yet match the field of view and redshift resolution …
