Quantifying Foreground Contamination in the Dark Ages 21 cm Power Spectrum Using an Electromagnetically Simulated Dipole Antenna Atop a Dielectric Surface
Willow Smith, Jonathan C. Pober, Bang D. Nahn +2
The highly-redshifted 21 cm signal from the cosmic Dark Ages presents an exciting frontier for cosmology, with the potential to observe a large number of Fourier modes of the cosmi…
The FarView Low Frequency Radio Array on the Moon's Far Side: Science and Array Architecture
Jack O. Burns, Judd Bowman, Tzu-Ching Chang +8
FarView is a proposed low frequency radio interferometer for deployment on the lunar far side, enabled by the Moon's radio quiet environment. Operating over 1-50 MHz inaccessible f…
The Impact of Foregrounds on Dark Ages Measurements with the Highly Redshifted 21 cm Line
Jonathan C. Pober, Willow Smith
Studies of the cosmic dark ages () using the highly redshifted 21 cm line of neutral hydrogen offer unparalleled amounts of cosmological information, an…
Detecting the 21 cm Signal of the Cosmic Dark Ages
Willow Smith, Jonathan C. Pober
The cosmic "Dark Ages" is the period between the last scattering of the Cosmic Microwave Background (CMB) and the appearance of the first luminous sources, spanning redshifts $1100…
