HI as a Probe of the Large Scale Structure in the Post-Reionization Universe: Visibility Correlations and Prospects for Detection
Nishikanta Khandai, Kanan K. Datta, J. S. Bagla
Simulated maps of the HI distribution in the post-reionization era are used to study the prospects for detection with existing and upcoming radio telescopes. We consider detection…
HI as a Probe of the Large Scale Structure in the Post-Reionization Universe
J. S. Bagla, Nishikanta Khandai, Kanan K. Datta
We model the distribution of neutral Hydrogen (HI hereafter) in the post-reionization universe. This model uses gravity only N-Body simulations and an ansatz to assign HI to dark m…
Hubble, Hubble's law and the expanding universe
J. S. Bagla
Hubble's name is associated closely with the idea of an expanding universe as he discovered the relation between the recession velocity and distances of galaxies. Hubble also did a…
Metal Enrichment and Reionization Constraints on Early Star Formation
J. S. Bagla, Girish Kulkarni, T. Padmanabhan
The epoch of reionization and formation of first stars are inter-linked topics that are of considerable interest. We use a simplified approach for studying formation of stars in co…
