A new goodness-of-fit statistic and its application to 21-cm cosmology
Keith Tauscher, David Rapetti, Jack O. Burns
The reduced chi-squared statistic is a commonly used goodness-of-fit measure, but it cannot easily detect features near the noise level, even when a large amount of data is availab…
Assessment of the Projection-induced Polarimetry Technique for Constraining the Foreground Spectrum in Global 21 cm Cosmology
Bang D. Nhan, David D. Bordenave, Richard F. Bradley +4
Detecting the cosmological sky-averaged (global) 21 cm signal as a function of observed frequency will provide a powerful tool to study the ionization and thermal history of the in…
A Ground Plane Artifact that Induces an Absorption Profile in Averaged Spectra from Global 21-cm Measurements - with Possible Application to EDGES
Richard F. Bradley, Keith Tauscher, David Rapetti +1
Most of the current Global 21-cm experiments include ground screens that help moderate effects from the Earth. In this paper, we report on a possible systematic artifact within the…
