Studying Cosmic Dawn using redshifted HI 21-cm signal: A brief review
Ankita Bera, Raghunath Ghara, Atrideb Chatterjee +2
In this review article, we briefly outline our current understanding of the physics associated with the HI 21-cm signal from cosmic dawn. We discuss different phases of cosmic dawn…
Bridging the Gap between Cosmic Dawn and Reionization favors Faint Galaxies-dominated Models
Ankita Bera, Sultan Hassan, Aaron Smith +4
It has been claimed that traditional models struggle to explain the tentative detection of the 21\,cm absorption trough centered at measured by the EDGES collaboration. O…
Impact of cosmic rays on the global 21-cm signal during cosmic dawn
Ankita Bera, Saumyadip Samui, Kanan K. Datta
It is extremely important to understand the processes through which the thermal state of the inter-galactic medium (IGM) evolved in the early universe in order to study the evoluti…
