Towards Detection of Redshifted 21-cm Signal from Cosmic Dawn and Epoch of Reionisation

JN Thekkeppattu - 2022 - espace.curtin.edu.au
The redshifted 21-cm signal from neutral hydrogen has the potential to provide valuable
information on the the periods of cosmic dawn and epoch of reionisation (CD/EoR). The sky …
