Extracting the Global 21-cm signal from Cosmic Dawn and Epoch of Reionization in the presence of Foreground and Ionosphere
Anshuman Tripathi, Abhirup Datta, Madhurima Choudhury +1
Detection of redshifted \ion{H}{i} 21-cm emission is a potential probe for investigating the Universe's first billion years. However, given the significantly brighter foreground, d…
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…
Observing the Reionization : Effect of Calibration and Position Errors on Realistic Observation Conditions
Aishrila Mazumder, Abhirup Datta, Arnab Chakraborty +1
Observation of the redshifted 21-cm signal from Cosmic Dawn and Epoch of Reionization is a challenging endeavor in observational cosmology. Presence of orders of magnitude brighter…
Redshifted 21-cm bispectrum: Impact of the source models on the signal and the IGM physics from the Cosmic Dawn
Mohd Kamran, Raghunath Ghara, Suman Majumdar +5
The radiations from the first luminous sources drive the fluctuations in the 21-cm signal at Cosmic Dawn (CD) via two dominant astrophysical processes i.e. the Ly coupling and X…
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…
