Neutral hydrogen in the post-reionization universe
Hamsa Padmanabhan
The evolution of neutral hydrogen (HI) across redshifts is a powerful probe of cosmology, large scale structure in the universe and the intergalactic medium. Using a data-driven ha…

Constraining the CO intensity mapping power spectrum at intermediate redshifts
Hamsa Padmanabhan
We compile available constraints on the carbon monoxide (CO) 1-0 luminosity functions and abundances at redshifts 0-3. This is used to develop a data driven halo model for the evol…

Cosmic Information, the Cosmological Constant and the Amplitude of primordial perturbations
T. Padmanabhan, Hamsa Padmanabhan
A unique feature of gravity is its ability to control the information accessible to any specific observer. We quantify the notion of cosmic information ('CosmIn') for an eternal ob…
