We present an analysis of 55 hours of drift-scan data from the Murchison Widefield Array (MWA), a precursor to the SKA. The observation spans right ascensions from $\alpha = 349.0^{\circ}$ to $70^{\circ}$, covering two well-studied MWA fields, EoR0 and EoR1, divided into 163 Pointing Centres (PCs), each corresponding to approximately 20 minutes of observation time. For each PC, we estimate...
While the detection of the power spectrum has been the primary goal of 21 cm observations, it does not tell us the whole story of the Epoch of Reionization (EoR). Bispectrum, the next higher-order statistic, can access the additional information on non-Gaussianity, mode coupling, and topology of HI distribution during the EoR. Observationally, the bispectrum can be computed from...
During the Epoch of Reionization, luminous galaxies and quasars are expected to produce large ionized regions embedded within the neutral intergalactic medium. Detecting these individual ionized bubbles in the redshifted HI 21-cm signal offers a direct probe of the ionizing sources and the evolving IGM. However, such detections remain challenging for current radio interferometers due to...
