Cross-correlation of the H i 21-cm signal and Lyα forest: a probe of cosmology

Tomographic intensity mapping of the HI using the redshifted 21-cm observations opens up a new window towards our understanding of cosmological background evolution and structure formation. This is a key science goal of several upcoming radio telescopes including the Square Kilometer Array (SKA). In this article, we focus on the post-reionization signal and investigate the cross correlating of the 21-cm signal with other tracers of the large scale structure. We consider the cross-correlation of the post-reionization 21-cm signal with the Lyman- α forest, Lyman-break galaxies and late time anisotropies in the CMBR maps like weak lensing and the integrated Sachs Wolfe effect. We study the feasibility of detecting the signal and explore the possibility of obtaining constraints on cosmological models using it
