Global 21-cm signal extraction from foreground and instrumental effects III: Utilizing drift-scan time dependence and full Stokes measurements
Keith Tauscher, David Rapetti, Jack O. Burns
When using valid foreground and signal models, the uncertainties on extracted signals in global 21-cm signal experiments depend principally on the overlap between signal and foregr…
Characterizing the Radio Quiet Region Behind the Lunar Farside for Low Radio Frequency Experiments
Neil Bassett, David Rapetti, Jack O. Burns +2
Low radio frequency experiments performed on Earth are contaminated by both ionospheric effects and radio frequency interference (RFI) from Earth-based sources. The lunar farside p…
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…
Global 21-cm signal extraction from foreground and instrumental effects I: Pattern recognition framework for separation using training sets
Keith Tauscher, David Rapetti, Jack O. Burns +1
The sky-averaged (global) highly redshifted 21-cm spectrum from neutral hydrogen is expected to appear in the VHF range of MHz and its spectral shape and strength are…
A Space-Based Observational Strategy for Characterizing the First Stars and Galaxies Using the Redshifted 21-cm Global Spectrum
Jack O. Burns, Richard Bradley, Keith Tauscher +19
The redshifted 21-cm monopole is expected to be a powerful probe of the epoch of the first stars and galaxies (). The global 21-cm signal is sensitive to the thermal and i…
