Studying neutral hydrogen structures during the epoch of reionization using fractal dimensions
Bidisha Bandyopadhyay, T. Roy Choudhury, T. R. Seshadri
Fractal dimensions can be used to characterize the clustering and lacunarities in density distributions. We use generalized fractal dimensions to study the neutral hydrogen distrib…
Clusters of galaxies and the cosmic web with SKA
Ruta Kale, K. S. Dwarakanath, Dharam Vir Lal +7
The intra-cluster and inter-galactic media (ICM, IGM) that pervade the large scale structure of the Universe are known to be magnetised at sub-micro Gauss to micro Gauss levels and…
The redshifted HI 21 cm signal from the post-reionization epoch: Cross-correlations with other cosmological probes
T. Guha Sarkar, K. K. Datta, A. K. Pal +2
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 f…
Line of sight anisotropies in the Cosmic Dawn and EoR 21-cm power spectrum
Suman Majumdar, Kanan K. Datta, Raghunath Ghara +5
The line of sight direction in the redshifted 21-cm signal coming from the cosmic dawn and the epoch of reionization is quite unique in many ways compared to any other cosmological…
Modelling the 21 cm Signal From the Epoch of Reionization and Cosmic Dawn
T. Roy Choudhury, Kanan Datta, Suman Majumdar +5
Studying the cosmic dawn and the epoch of reionization through the redshifted 21 cm line are among the major science goals of the SKA1. Their significance lies in the fact that the…
Probing individual sources during reionization and cosmic dawn using SKA HI 21-cm observations
Kanan K. Datta, Raghunath Ghara, Suman Majumdar +4
Detection of individual luminous sources during the reionization epoch and cosmic dawn through their signatures in the HI 21-cm signal is one of the direct approaches to probe the…
