High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization

Rennan Barkana, Oliver Basquette, Ankita Bera +22

In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…

Overview of 21cm Experiments at high redshift with SKAO

CD Science Working Group, Gianni Bernardi, Daniela Breitman +81

We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…

Implications of SARAS3 data for Coulomb-like interacting dark matter

Shikhar Mittal, Prakhar Bansal, Harry Bevins +1

The 21-cm signal from cosmic dawn is a potentially sensitive probe of interactions between dark matter (DM) and baryons. We investigate the implications of the SARAS3 non-detection…

Optimisation of calibration sources for global 21-cm experiments: the REACH case

Adarsh Kumar Dash, Dominic Anstey, Harry T. J. Bevins +41

The spin-flip 21-cm signal from the Cosmic Dawn and the Epoch of Reionization is an essential probe of the conditions that led to the formation of the first luminous objects in the…

Circuit Modeling for In Situ 21 cm Radiometer Calibration

Gary Vincent Charles Allen, Saurabh Pegwal, Dirk de Villiers +42

Recent experiments in cosmology, particularly those aimed at detecting the faint, redshifted, global 21 cm hydrogen line (depth < ~200 mK, z > 7.5), have imposed stringent new requ…
