Visibility-based Power Spectrum Estimation for Low-Frequency Radio Interferometric Observations
Samir Choudhuri
We present a visibility based estimator namely, the Tapered Gridded Estimator (TGE) to estimate the power spectrum of the diffuse sky signal. The TGE has three novel features. Firs…

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…
