Nearly pristine gas in a galaxy 1 billion years after the Big Bang
Sarah E. I. Bosman, Frederick B. Davies, Louise Welsh +22
Excitation of carbon and oxygen ions is the primary mechanism by which collapsing gas clouds dissipate heat to form new stars. At early cosmic times, in galaxies with chemically pr…
Stacking HI in the dark: Towards detecting the reionization-epoch 21 cm signal in Lyman- dark gaps
Barun Maity, Frederick B. Davies
The detection of the redshifted 21 cm signal from neutral hydrogen during the epoch of reionization remains one of the central challenges in contemporary cosmology. Although upcomi…
Square Kilometer Array Synergies for the Epoch of Reionization and Cosmic Dawn
Anirban Chakraborty, Tirthankar R. Choudhury, Kanan K. Datta +15
Synergies with other instruments will be essential in making, verifying, and interpreting a detection of the cosmic 21-cm signal from the Epoch of Reionization (EoR) and Cosmic Daw…
Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
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…
Exploring the Cosmic Dawn through the 21 cm Forest and High-redshift Radio Sources with the SKA
Junsong Cang, Benedetta Ciardi, Barun Maity +12
The 21~cm forest, seen as absorption features in the spectra of distant radio sources, is produced by intervening neutral hydrogen and offers a direct probe of the neutral intergal…
Impact of Primordial Black Hole population on 21 cm observables at high redshift
Atrideb Chatterjee, Barun Maity, Koushiki
The 21-centimetre (21-cm) signal is one of the most promising probes of the high-redshift Universe. It has typically been modelled without accounting for the effects of active gala…
Studying dark gaps in Ly- forest transmission with large reionization simulations
Barun Maity, Frederick B. Davies, Benedetta Spina +1
The physical conditions of the intergalactic medium (IGM) during the final stages of cosmic reionization () are not yet fully understood. Recent reports of unexpected…
