Probing early universe through redshifted 21-cm signal: Modelling and observational challenges
Abinash Kumar Shaw, Arnab Chakraborty, Mohd Kamran +8
The redshifted 21-cm radiation from the atomic hydrogen (HI) provides an excellent direct probe to study the evolution of HI in IGM and thus reveal the nature of the first luminous…
Statistical analysis of the causes of excess variance in the 21 cm signal power spectra obtained with the Low-Frequency Array
H. Gan, L. V. E Koopmans, F. G. Mertens +11
The detection of the 21 cm signal of neutral hydrogen from the Epoch of Reionization (EoR) is challenging due to bright foreground sources, radio frequency interference (RFI), the…
A numerical study of 21-cm signal suppression and noise increase in direction-dependent calibration of LOFAR data
M. Mevius, F. Mertens, L. V. E. Koopmans +14
We investigate systematic effects in direction dependent gain calibration in the context of the Low-Frequency Array (LOFAR) 21-cm Epoch of Reionization (EoR) experiment. The LOFAR…
Demonstrating the Tapered Gridded Estimator (TGE) for the Cosmological HI 21-cm Power Spectrum using GMRT observations
Srijita Pal, Somnath Bharadwaj, Abhik Ghosh +1
We apply the Tapered Gridded Estimator (TGE) for estimating the cosmological 21-cm power spectrum from GMRT observations which corresponds to the neutral hydroge…
