Calibration requirement for Epoch of Reionization 21-cm signal observation -- III. Bias and variance in uGMRT ELAIS-N1 field power spectrum
Saikat Gayen, Rashmi Sagar, Sarvesh Mangla +6
Power spectrum of \HI 21-cm radiation is one of the promising probes to study large scale structure of the universe and understand galaxy formation and evolution. The presence of f…
Calibration requirements for Epoch of Reionization 21-cm signal observations -- II. Analytical estimation of the bias and variance with time-correlated residual gains
Jais Kumar, Prasun Dutta, Samir Choudhuri +1
Observation of redshifted 21-cm signals from neutral hydrogen holds the key to understanding the structure formation and its evolution during the reionization and post-reionization…
Calibration Requirements for Epoch of Reionization 21-cm signal observations -- I. Effect of time-correlated gains
Jais Kumar, Prasun Dutta, Nirupam Roy
The residual gain errors add to the systematics of the radio interferometric observations. In case of the high dynamic range observations, these systematic effects dominates over t…
