Joint Estimation of Properties of the Lunar Subsurface and Galactic Foregrounds with LuSEE-Night
Fatima Yousuf, Zack Li, Stuart D. Bale +36
The Lunar Surface Electromagnetics Experiment (LuSEE-Night) is a joint NASA-DOE-ESA low-frequency radio telescope that will reach the lunar far side in 2027. The unknown dielectric…
The Radio-wave Observations at the Lunar Surface of the photoElectron Sheath (ROLSES) instrument onboard the Intuitive Machines-1 Mission to the Moon
Nat Gopalswamy, Robert J. MacDowall, Pertti A. Mäkelä +15
The Radio wave Observations at the Lunar Surface of the photoElectron Sheath (ROLSES) instrument is a radio telescope system designed to characterize the radio and plasma wave envi…
Studying Exoplanets in the Radio from the Moon
Jake D. Turner, Jack O. Burns, David Rapetti +12
Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. Therefore, there is great need to directly constrain these fields to holist…
Linear map-making with LuSEE-Night
Hugo Camacho, Kaja M. Rotermund, Anže Slosar +32
LuSEE-Night is a pathfinder radio telescope on the lunar far side employing four 3-m monopole antennas arranged as two horizontal cross pseudo-dipoles on a rotational stage and sen…
Results from NASA's First Radio Telescope on the Moon: Terrestrial Technosignatures and the Low-Frequency Galactic Background Observed by ROLSES-1 Onboard the Odysseus Lander
Joshua J. Hibbard, Jack O. Burns, Robert MacDowall +8
Radiowave Observations on the Lunar Surface of the photo-Electron Sheath instrument (ROLSES- 1) onboard the Intuitive Machines' Odysseus lunar lander represents NASA's first radio…
: A New Model for Emulating Radio Antenna Beam Patterns for 21-cm Cosmology and Antenna Design Studies
Joshua J. Hibbard, Bang D. Nhan, David Rapetti +1
In 21-cm experimental cosmology, accurate characterization of a radio telescope's antenna beam response is essential to measure the 21-cm signal. Computational electromagnetic (CEM…
Validating posteriors obtained by an emulator when jointly-fitting mock data of the global 21-cm signal and high-z galaxy UV luminosity function
J. Dorigo Jones, D. Rapetti, J. Mirocha +3
Although neural-network-based emulators enable efficient parameter estimation in 21-cm cosmology, the accuracy of such constraints is poorly understood. We employ nested sampling t…
Fitting and Comparing Galactic Foreground Models for Unbiased 21-cm Cosmology
Joshua J. Hibbard, David Rapetti, Jack O. Burns +2
Accurate detection of the cosmological 21-cm global signal requires galactic foreground models which can remove power over ~. Although foreground and global signal models una…
LuSEE 'Night': The Lunar Surface Electromagnetics Experiment
Stuart D. Bale, Neil Bassett, Jack O. Burns +18
The Lunar Surface Electromagnetics Explorer 'LuSEE Night' is a low frequency radio astronomy experiment that will be delivered to the farside of the Moon by the NASA Commercial Lun…
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…
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…
