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…

Nearest Neighbour-Based Statistics for 21cm-Galaxy Cross-Correlations in the Epoch of Reionization

Anirban Chakraborty, Kwanit Gangopadhyay, Arka Banerjee +1

21cm radiation from neutral hydrogen serves as a direct probe of the Epoch of Reionization. However, both its detection and physical interpretation are severely hindered by contami…

Capturing Small-Scale Reionization Physics: A Sub-Grid Model for Photon Sinks with SCRIPT

Tirthankar Roy Choudhury, Anirban Chakraborty

The epoch of reionization represents a major phase transition in cosmic history, during which the first luminous sources ionized the intergalactic medium (IGM). However, the small-…

Reionization and its sources

Anirban Chakraborty, Tirthankar Roy Choudhury

Reionization represents an important phase in the history of our Universe when ultraviolet radiation from the first luminous sources, primarily stars and accreting black holes, ion…
