Probing dark energy using anisotropies in the clustering of post-EoR HI distribution

Abstract

We propose an anisotropy quantifier of the HI 21-cm signal traditionally used to clock the astrophysics of the reionization era as a post-reionization dark energy diagnostic. We find that the anisotropy probe can be measured at SNR $\sim 10$ in both auto-correlation and in cross-correlation with the Ly-$\alpha$ forest over a wide $z$ and $k-$range. We propose to use the BAO signature on the anisotropy signal to measure $(H(z),D_A(z))$. Subsequently, we put constraints on a dark energy model involving a negative cosmological constant on top of a quintessence scalar field and find that such a model is consistent with futuristic observations.
