Impact of numerical stability in Bayesian noise wave calibration on global 21-cm experiments
Saswata Dasgupta, Adarsh Kumar Dash, Dominic Anstey +3
The paper identifies and mitigates a numerical instability in the Bayesian noise‑wave calibration used for global 21‑cm experiments, improving reproducibility and accuracy of recei…
Global 21cm Measurement Calibration Methodology
Martin Bucher, Christian J. Kirkham, Eloy de Lera Acedo +2
The paper derives explicit calibration equations for global 21 cm signal experiments, reconciling earlier approaches with amplifier noise formalism and providing a Möbius‑geometry…
Direct Primary Beam Correction: Untangling Mutual Coupling in 21-cm Cosmological Experiments with the SKA-Low Radio Telescope
Oscar S. D. O'Hara, Quentin Gueuning, Eloy de Lera Acedo +7
The paper presents Direct Primary Beam Correction, a method that uses regularized inversion of stacked Jones matrices to reconstruct and correct the far‑field beam pattern of SKA‑L…
Synchrotron and free-free mapping with simulated REACH observations between 50-170 MHz
Daniel Robins, Dominic Anstey, Harry Bevins +2
Global 21cm experiments aim to detect the hydrogen 21cm signal by separating it from foreground emission that can be orders of magnitude brighter than the signal. REACH (the Radio…
Bayesian model comparison and validation with Gaussian Process Regression for interferometric 21-cm signal recovery
Yuchen Liu, Eloy de Lera Acedo, Peter Sims
The 21-cm signal from neutral hydrogen traces the formation and evolution of early cosmic structures during the Cosmic Dawn and the subsequent Epoch of Reionization. However, the i…
Overview of 21cm Experiments at high redshift with SKAO
CD Science Working Group, Gianni Bernardi, Daniela Breitman +81
We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…
