Improving constraints on the reionization parameters using 21-cm bispectrum
Himanshu Tiwari, Abinash Kumar Shaw, Suman Majumdar +2
Radio interferometric experiments aim to constrain the reionization model parameters by measuring the 21-cm signal statistics, primarily the power spectrum. However the Epoch of Re…
A fast estimator for quantifying the shape dependence of the 3D bispectrum
Abinash Kumar Shaw, Somnath Bharadwaj, Debanjan Sarkar +3
The dependence of the bispectrum on the size and shape of the triangle contains a wealth of cosmological information. Here we consider a triangle parameterization which allows us t…
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…
