Detecting the 21 cm Signal from the Cosmic Dark Ages
The cosmic “dark ages” is the period between the last scattering of the cosmic microwave background and the appearance of the first luminous sources, spanning redshifts 1100 ≳ z ≳ 30. The only way to observe this period is by examining the 21 cm hyperfine transition line of neutral hydrogen H i ,...
