A Tapered Gridded Estimator (TGE) for the Multi-Frequency Angular Power Spectrum (MAPS) and the Cosmological HI 21-cm Power Spectrum
Somnath Bharadwaj, Srijita Pal, Samir Choudhuri +1
In this work we present a new approach to estimate the power spectrum of redshifted HI 21-cm brightness temperature fluctuations. The MAPS complete…

An Image-based Tapered Gridded Estimator (ITGE) for the angular power spectrum
Samir Choudhuri, Prasun Dutta, Somnath Bharadwaj
We present the Image-based Tapered Gridded Estimator (ITGE) to measure the angular power spectrum of the sky signal directly from the visibilities measured in radio-in…

Estimating statistics of sky brightness using radio interferometric observations
Prasun Dutta, Meera Nandakumar
Radio interferometric data are used to estimate the sky brightness distributions in radio frequencies. Here we focus on estimators of the large-scale structure and the power spectr…
