Before it becomes a sensitive probe of the epoch of reionization, the dark ages and fundamental physics, 21-cm tomography must successfully contend with the issue of foreground contamination. Broad-band foreground sources are expected to be roughly 4 orders of magnitude larger than any cosmological signals, so precise foreground models will be necessary. Such foreground models often contain a large number of parameters, reflecting the complicated physics that governs foreground sources. In this… Expand

Global 21 cm signal experiments: A designer’s guide
TLDR
A systematic mathematical framework for global signal data analysis is established that removes foregrounds in an optimal manner, complementing spectra with angular information, and shows that if observations and data analysis algorithms are optimized based on these findings, an instrument with a 5 � wide beam can achieve highly significant detections.
