Optimisation of calibration sources for global 21-cm experiments: the REACH case
Adarsh Kumar Dash, Dominic Anstey, Harry T. J. Bevins +41
The spin-flip 21-cm signal from the Cosmic Dawn and the Epoch of Reionization is an essential probe of the conditions that led to the formation of the first luminous objects in the…
Circuit Modeling for In Situ 21 cm Radiometer Calibration
Gary Vincent Charles Allen, Saurabh Pegwal, Dirk de Villiers +42
Recent experiments in cosmology, particularly those aimed at detecting the faint, redshifted, global 21 cm hydrogen line (depth < ~200 mK, z > 7.5), have imposed stringent new requ…
RFSoC receiver calibration system for 21-cm global spectrum experiments from space: The CosmoCube case
Jiacong Zhu, Eloy de Lera Acedo, Kaan Artuc +1
The CosmoCube project plans to deploy a global 21-cm spectrometer with 10-100 MHz observation band in a lunar orbit. The farside part of such an orbit, i.e. the part of orbit behin…
Accounting for Noise and Singularities in Bayesian Calibration Methods for Global 21-cm Cosmology Experiments
Christian J. Kirkham, William J. Handley, Jiacong Zhu +6
Due to the large dynamic ranges involved with separating the cosmological 21-cm signal from the Cosmic Dawn from galactic foregrounds, a well-calibrated instrument is essential to…
The Electrical Design of a Membrane Antenna for Lunar-based Low-frequency Radio Telescope
Suonanben, Fengquan Wu, Kai He +15
Detecting primordial fluctuations from the cosmic dark ages requires extremely large low-frequency radio telescope arrays deployed on the far side of the Moon. The antenna of such…
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…
