Bayesian data analysis for sky-averaged 21-cm experiments with contamination from linearly polarised foreground
Emma Shen, Dominic Anstey, Marta Spinelli +2
The precise measurement of the sky-averaged HI absorption signal between 50 and 200 MHz is the primary goal of global 21-cm cosmology. This measurement has the potential to unravel…
Global 21 cm Signal Recovery Under Changing Environmental Conditions
Joe H. N. Pattison, Jean Cavillot, Harry T. J. Bevins +2
The redshifted 21 cm line of cosmic atomic hydrogen is one of the most auspicious tools in deciphering the early Universe. Recovering this signal remains an ongoing problem for cos…
Impact of extragalactic point sources on the low-frequency sky spectrum and cosmic dawn global 21-cm measurements
Shikhar Mittal, Girish Kulkarni, Dominic Anstey +1
Contribution of resolved and unresolved extragalactic point sources to the low-frequency sky spectrum is a potentially non-negligible part of the astrophysical foregrounds for cosm…
Understanding spectral artefacts in SKA-LOW 21-cm cosmology experiments: the impact of cable reflections
Oscar Sage David O'Hara, Fred Dulwich, Eloy de Lera Acedo +4
The Cosmic Dawn was marked by the formation of the first stars, and preceded the Epoch of Reionization (EoR), when the Universe underwent a fundamental transformation caused by the…
