Global 21 cm Signal Recovery Under Changing Environmental Conditions

Joe H. N. Pattison, Jean Cavillot, Harry T. J. Bevins +2

The redshifted 21 cm line of cosmic atomic hydrogen is one of the most auspicious tools in deciphering the early Universe. Recovering this signal remains an ongoing problem for cos…

A Broadband Multipole Method for Accelerated Mutual Coupling Analysis of Large Irregular Arrays Including Rotated Antennas

Quentin Gueuning, Eloy de Lera Acedo, Anthony Keith Brown +2

We present a numerical method for the analysis of mutual coupling effects in large, dense and irregular arrays with identical antennas. Building on the Method of Moments (MoM), our…

Impact of extragalactic point sources on the low-frequency sky spectrum and cosmic dawn global 21-cm measurements

Shikhar Mittal, Girish Kulkarni, Dominic Anstey +1

Contribution of resolved and unresolved extragalactic point sources to the low-frequency sky spectrum is a potentially non-negligible part of the astrophysical foregrounds for cosm…

The Spectrometer Development of CosmoCube, Lunar Orbiting Satellite to Detect 21-cm Hydrogen Signal from Cosmic Dark Ages

Kaan Artuc, Eloy de Lera Acedo

The cosmic Dark Ages represent a pivotal epoch in the evolution of the Universe, marked by the emergence of the first cosmic structures under the influence of dark matter. The 21-c…

Calibration Error in 21-centimeter Global Spectrum Experiments

Shijie Sun, Eloy de Lera Acedo, Fengquan Wu +3

The redshifted 21 cm line signal is a powerful probe of the cosmic dawn and the epoch of reionization. The global spectrum can potentially be detected with a single antenna and spe…
