Observations of the Cosmic Dawn and Epoch of Reionization with the SKAO: Observational Lessons Learned from Precursors and Pathfinder Instruments
Eloy de Lera Acedo, James Aguirre, Dominic Anstey +34
This chapter summarizes the observational lessons learned after two decades of observations of the Cosmic Dawn (CD) and Epoch of Reionization (EoR) with SKAO pathfinders and precur…
The Tracking Tapered Gridded Estimator for the 21-cm power spectrum from the Murchison Widefield Array (MWA) drift scan observations -- III. Improved upper limits at from multiple pointings
Shouvik Sarkar, Khandakar Md Asif Elahi, Samir Choudhuri +5
We analyze zenith-pointing Murchison Widefield Array (MWA) drift scan observations covering wit…
A measurement of Galactic synchrotron emission using MWA drift scan observations
Suman Chatterjee, Shouvik Sarkar, Samir Choudhuri +4
Studying the diffuse Galactic synchrotron emission (hereafter, DGSE) at arc-minute angular scale is important to remove the foregrounds for the cosmological 21-cm observations. Sta…
The Tracking Tapered Gridded Estimator for the 21-cm power spectrum from MWA drift scan observations II: The Missing Frequency Channels
Khandakar Md Asif Elahi, Somnath Bharadwaj, Suman Chatterjee +4
Missing frequency channels pose a problem for estimating the redshifted 21-cm power spectrum (PS) from radio-interferometric visibility data. This is parti…
