A 21-cm power spectrum at 48 MHz, using the Owens Valley Long Wavelength Array
Hugh Garsden, Lincoln Greenhill, Gianni Bernardi +6
The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, 15-30. Using observations mad…

Spectral index of the Galactic foreground emission in the 50-87 MHz range
Marta Spinelli, Gianni Bernardi, Hugh Garsden +4
Total-power radiometry with individual meter-wave antennas is a potentially effective way to study the Cosmic Dawn () through measurement of sky brightness arising from th…

Simulations of Galactic polarized synchrotron emission for Epoch of Reionization observations
M. Spinelli, G. Bernardi, M. G. Santos
The detection of the redshifted cosmological ~cm line signal requires the removal of the Galactic and extragalactic foreground emission, which is orders of magnitude brighter a…
