TL;DR: In this article, the authors used the ground avoidance technique to estimate the spherically averaged 21 cm power spectra at the European Large Area ISO Survey-North 1 (ELAIS-N1) field.
Journal ArticleDOI
A Tapered Gridded Estimator (TGE) for the multifrequency angular power spectrum (MAPS) and the cosmological H I 21-cm power spectrum
TL;DR: In this article, a new approach to estimate the power spectrum of redshifted HI 21-cm brightness temperature fluctuations is presented, which is based on the Fourier transform of the sky signal.
Journal ArticleDOI
Demonstrating the Tapered Gridded Estimator (TGE) for the cosmological H i 21-cm power spectrum using 150-MHz GMRT observations
TL;DR: In this paper, the authors apply the TGE for estimating the cosmological 21-cm power spectrum from GMRT observations which corresponds to the neutral hydrogen (HI) at redshift $z = 8.28.
