Properties and limitations of linear models for mutual coupling in 21 cm arrays

Vincent MacKay, Robert Pascua, Eleanor Rath +7

Mutual coupling between elements of low-frequency arrays is a leading systematic for 21 cm cosmology, leaking bright foregrounds into otherwise clean regions of the power spectrum.…

Quantifying Sky Map Resolution Requirements for Beam Chromaticity Correction in Sky-Averaged 21 cm Experiments

Aleksandra Dragović, Dominic Anstey, Harry T. J. Bevins +1

The 21 cm hyperfine transition of neutral hydrogen provides one of the few direct probes of the early cosmic history. High-redshift detections of this signal could shine light on t…

The MegaWave Radio Surveyor

T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40

Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…

Optimizing Foreground Modelling for Global 21cm Cosmology with GPU-Accelerated Nested Sampling

Jacob L. Tutt, Peter H. Sims, Joe H. N. Pattison +3

The global 21-cm signal provides a powerful probe of early-Universe astrophysics, but its detection is hindered by Galactic foregrounds that are orders of magnitude brighter than t…

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…

The mass distribution of the first stars can be determined via the 21-cm signal

T. Gessey-Jones, N. S. Sartorio, H. T. J. Bevins +6

The formation of the first stars and the subsequent population of X-ray binaries represents a fundamental transition in the state of the Universe as it evolves from near homogeneit…
