The Effect of Large Optical Depths on the Non-Gaussian 21-cm signal from Cosmic Dawn
Iffat Nasreen, Kanan K. Datta, Abinash K. Shaw +6
During the Cosmic Dawn (CD), the HI 21-cm optical depth ( ) in the intergalactic medium can become significantly large. Consequently, the second and higher-order terms of ap…
