The rich complexity of 21-cm fluctuations produced by the first stars
The rich complexity of 21-cm fluctuations produced by the first stars
We explore the complete history of the 21 cm signal in the redshift range z = 7–40. This redshift range includes various epochs of cosmic evolution related to primordial star formation, and should be accessible to existing or planned low-frequency radio telescopes. We use semi-numerical computational methods to explore the …
