Testing common approximations to predict the 21cm signal at the Epoch of Reionization and Cosmic Dawn
Timothée Schaeffer, Sambit K. Giri, Aurel Schneider
Predicting the 21cm signal from the epoch of reionization and cosmic dawn is a complex and challenging task. Various simplifying assumptions have been applied over the last decades…

The 21-cm signal during the end stages of reionization
Sambit K. Giri, Michele Bianco, Timothée Schaeffer +3
During the epoch of reionization (EoR), the 21-cm signal allows direct observation of the neutral hydrogen (HI) in the intergalactic medium (IGM). In the post-reionization era, thi…
