Constraining Warm Dark Matter and Pop III stars with the Global 21-cm Signal
Joshua J. Hibbard, Jordan Mirocha, David Rapetti +3
Upcoming ground and space-based experiments may have sufficient accuracy to place significant constraints upon high-redshift star formation, Reionization, and dark matter (DM) usin…
Lost Horizon: Quantifying the Effect of Local Topography on Global 21-cm Cosmology Data Analysis
Neil Bassett, David Rapetti, Keith Tauscher +4
We present an investigation of the horizon and its effect on global 21-cm observations and analysis. We find that the horizon cannot be ignored when modeling low frequency observat…
Global 21-cm signal extraction from foreground and instrumental effects IV: Accounting for realistic instrument uncertainties and their overlap with foreground and signal models
Keith Tauscher, David Rapetti, Bang D. Nhan +6
All 21-cm signal experiments rely on electronic receivers that affect the data via both multiplicative and additive biases through the receiver's gain and noise temperature. While…
Global 21-cm Cosmology from the Farside of the Moon
Jack Burns, Stuart Bale, Richard Bradley +12
One of the last unexplored windows to the cosmos, the Dark Ages and Cosmic Dawn, can be opened using a simple low frequency radio telescope from the stable, quiet lunar farside to…
Ensuring Robustness in Training Set Based Global 21-cm Cosmology Analysis
Neil Bassett, David Rapetti, Keith Tauscher +2
We present a methodology for ensuring the robustness of our analysis pipeline in separating the global 21-cm hydrogen cosmology signal from large systematics based on singular valu…
Modelling the Galactic Foreground and Beam Chromaticity for Global 21-cm Cosmology
Joshua J. Hibbard, Keith Tauscher, David Rapetti +1
In order to characterize and model the beam-weighted foreground for global 21-cm signal experiments, we present a methodology for generating basis eigenvectors that combines analyt…
