Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys
Leon Noble, Suman Majumdar, Matteo Viel +7
The redshifted 21cm signal from the post-reionization epoch is highly non-Gaussian; thus, higher-order statistics, such as the bispectrum, are required to extract this non-Gaussian…
Simulations of the 21cm emission line for upcoming large-scale HI galaxy surveys
Joël Mayor, Marta Spinelli, Gabriella De Lucia +5
Upcoming galaxy surveys with the SKA Observatory will detect neutral hydrogen (HI) across unprecedented volumes, and their scientific return will crucially depend on predictive mod…
Bayesian data analysis for sky-averaged 21-cm experiments with contamination from linearly polarised foreground
Emma Shen, Dominic Anstey, Marta Spinelli +2
The precise measurement of the sky-averaged HI absorption signal between 50 and 200 MHz is the primary goal of global 21-cm cosmology. This measurement has the potential to unravel…
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…
