Validating a novel angular power spectrum estimator using simulated low frequency radio-interferometric data
Samir Choudhuri, Nirupam Roy, Somnath Bharadwaj +3
The "Tapered Gridded Estimator" (TGE) is a novel way to directly estimate the angular power spectrum from radio-interferometric visibility data that reduces the computation by effi…

The angular power spectrum measurement of the Galactic synchrotron emission in two fields of the TGSS survey
Samir Choudhuri, Somnath Bharadwaj, Sk. Saiyad Ali +3
Characterizing the diffuse Galactic synchrotron emission at arcminute angular scales is needed to reliably remove foregrounds in cosmological 21-cm measurements. The study of this…

Fisher Matrix Based Predictions for Measuring the z = 3.35 Binned 21-cm Power Spectrum using the Ooty Wide Field Array (OWFA)
Anjan Kumar Sarkar, Somnath Bharadwaj, Sk. Saiyad Ali
We use the Fisher matrix formalism to predict the prospects of measuring the redshifted 21-cm power spectrum in different -bins using observations with the upcoming Ooty Wide Fi…
