| Abstract: | The period in the evolution of the universe when the first stars began appearing is called cosmic dawn; these sources generated photons which started ionizing the intergalactic medium (IGM) from almost completely neutral to highly ionized, this is the epoch of reionisation in the history of the universe. One of the key science goals for several existing as well as upcoming telescopes is to probe into this era of the history of the universe. Radio telescopes mainly do this by detecting the redshifted 21-cm hyperfine line of neutral hydrogen (referred to as HI 21-cm line). © 2019 URSI. All rights reserved. |
