Intergalactic heating by Lyα photons including hyperfine structure corrections

Research output: Contribution to journalArticle

Abstract / Description of output

Lyα photons from the first radiating sources in the Universe play a pivotal role in 21-cm radio detections of Cosmic Dawn and the Epoch of Reionization. Comments are provided on the effect of the hyperfine structure of hydrogen on the rate of heating or cooling of the Intergalactic Medium by Lyα photons.
