Intensity mapping of post-reionization 21-cm signal and its cross-correlations as a probe of gravity
Chandrachud B. V. Dash, Tapomoy Guha Sarkar, Anjan Kumar Sarkar
We propose the intensity mapping of the redshifted HI 21-cm signal from the post-reionization epoch as a cosmological probe of gravity. We consider the Hu-Sawicki class of $…

Constraining dark energy using the cross correlations of weak lensing with post-reionization probes of neutral hydrogen
Chandrachud B. V. Dash, Tapomoy Guha Sarkar
We investigate the prospects of detecting the cross correlation of CMBR weak-lensing convergence field with the large scale tracers of the underlying dark matter distribution in th…
