Impact of astrophysical scatter on the Epoch of Reionization [H I] bispectrum
Chandra Shekhar Murmu, Kanan K. Datta, Suman Majumdar +1
It is believed that the first star-forming galaxies are the main drivers of cosmic reionization. It is usually assumed that there is a one-to-one relationship between the star form…
The monopole and quadrupole moments of the Epoch of Reionization (EoR) 21-cm bispectrum
Sukhdeep Singh Gill, Suman Pramanick, Somnath Bharadwaj +2
We study the monopole () and quadrupole () moments of the 21-cm bispectrum (BS) from EoR simulations and present results for squeezed and stretched triang…
The morphology of the redshifted 21-cm signal from the Cosmic Dawn
Raghunath Ghara, Satadru Bag, Saleem Zaroubi +1
The spatial fluctuations in the tomographic maps of the redshifted 21-cm signal from the Cosmic Dawn (CD) crucially depend on the size and distribution of the regions with gas temp…
Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics -- I: Impact of the synthetic SKA1-Low observations
Saswata Dasgupta, Samit Kumar Pal, Satadru Bag +7
We analyse the evolution of the largest ionized region using the topological and morphological evolution of the redshifted 21-cm signal coming from the neutral hydrogen distributio…
