Observations in the 21-cm line can probe different phases of reionization: an initial one where the atomic medium is cold and is seen in absorption at the highest redshifts, and the later signal of 21-cm emission from a heated medium before it is ionized. The emission signal is the easier one to observe in upcoming years, and it can arise from low-density regions that are less ionized...
