The Epoch of Reionization 21-cm Bispectrum: The impact of light-cone effects and detectability
Rajesh Mondal, Garrelt Mellema, Abinash Kumar Shaw +2
We study the spherically averaged bispectrum of the 21-cm signal from the Epoch of Reionization (EoR). This metric provides a quantitative measurement of the level of non-Gaussiani…
The impact of non-Gaussianity on the Epoch of Reionization parameter forecast using 21-cm power spectrum measurements
Abinash Kumar Shaw, Somnath Bharadwaj, Rajesh Mondal
Measurements of the Epoch of Reionization (EoR) 21-cm signal hold the potential to constrain models of reionization. In this paper we consider a reionization model with three astro…
Predictions for measuring the 21-cm multi-frequency angular power spectrum using SKA-Low
Rajesh Mondal, Abinash Kumar Shaw, Ilian T. Iliev +5
The light-cone (LC) effect causes the mean as well as the statistical properties of the redshifted 21-cm signal to change with frequency (or cosmic t…
The impact of non-Gaussianity on the error covariance for observations of the Epoch of Reionization 21-cm power spectrum
Abinash Kumar Shaw, Somnath Bharadwaj, Rajesh Mondal
Recent simulations show the Epoch of Reionization (EoR) 21-cm signal to be inherently non-Gaussian whereby the error covariance matrix of the 21-cm power spectrum…
A method to determine the evolution history of the mean neutral Hydrogen fraction
Rajesh Mondal, Somnath Bharadwaj, Ilian T. Iliev +4
The light-cone (LC) effect imprints the cosmological evolution of the redshifted 21-cm signal along the frequency axis which is the line of sight (L…
