SCRIPT in the Cosmic Dawn: Distinguishing Redshift-Evolving Galaxy Populations with 21-cm Fluctuations
Janakee Raste, Tirthankar Roy Choudhury
Recent James Webb Space Telescope (JWST) observations suggest an unexpectedly high abundance of luminous galaxies at , challenging traditional models of star formatio…
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…
21 cm Signal from the Thermal Evolution of Lyman- during Cosmic Dawn
Janakee Raste, Shiv K. Sethi
The Lyman- photons couple the spin temperature of neutral hydrogen (HI) to the kinetic temperature during the era of cosmic dawn. During this process, they also exchange energy…
Thermal Evolution of the IGM due to Lyman-α photons during the Cosmic Dawn
Janakee Raste, Anjan Kumar Sarkar, Shiv K. Sethi
The first star-forming objects which formed at high redshifts during the cosmic dawn (CD) also emitted photons between Lyman- and Lyman-limit frequencies. These photons are ins…
