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…

Turbulent power spectrum in warm and cold neutral medium using the Galactic HI 21 cm emission
Samir Choudhuri, Nirupam Roy
Small-scale fluctuations of different tracers of the interstellar the medium can be used to study the nature of turbulence in astrophysical scales. Of these, the `continuum' emissi…
