Validation of the hera phase i epoch of reionization 21 cm power spectrum software pipeline
(IOP Publishing, 2022)
We describe the validation of the HERA Phase I software pipeline by a series of modular tests, building up to an
end-to-end simulation. The philosophy of this approach is to validate the software and algorithms used in ...
Breaking baryon-cosmology degeneracy with the electron density power spectrum
(IOP Publishing, 2022)
Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics
that are robust against these uncertainties, or ...
Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
(IOP Publishing, 2022)
The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be
conducted in the coming years by the SKAO and ...
