Modelling the post-reionization neutral hydrogen ($\mathrm{HI}$) 21-cm bispectrum

Abstract

Measurements of the post-reionization 21-cm bispectrum $B_{\mathrm{HI}}({\mathbf{k}}_1,{\mathbf{k}}_2,{\mathbf{k}}_3)$ using various upcoming intensity mapping experiments hold the potential for determining the cosmological parameters at a high level of precision. In this paper we have estimated the 21-cm bispectrum in the $z$ range $1\le z\le 6$ using semi-numerical simulations of the neutral hydrogen ($\mathrm{HI}$) distribution. We determine the $k$ and $z$ range where the 21-cm bispectrum can be adequately modelled using the predictions of second order perturbation theory, and we use this to predict the redshift evolution of the linear and quadratic $\mathrm{HI}$ bias parameters $b_1$ and $b_2$ respectively. The $b_1$ values are found to decreases nearly linearly with decreasing $z$, and are in good agreement with earlier predictions obtained by modelling the 21-cm power spectrum $P_{\mathrm{HI}}(k)$. The $b_2$ values fall sharply with decreasing $z$, becomes zero at $z\sim 3$ and attains a nearly constant value $b_2\approx -0.36$ at $z<2$. We provide polynomial fitting formulas for $b_1$ and $b_2$ as functions of $z$. The modelling presented here is expected to be useful in future efforts to determine cosmological parameters and constrain primordial non-Gaussianity using the 21-cm bispectrum.
