WebFeb 14, 2024 · Constructing a corrective transfer function using mock signal injection into the contaminated data has been a practice relied on for HI intensity mapping experiments. However, assessing whether this approach is viable for future intensity mapping surveys where precision cosmology is the aim, remains unexplored. Webforecast to be achievable by the oncoming generation of intensity mapping experiments. We focus on intensity maps of the redshifted 21 cm line radiation of neutral hydrogen (Hi) in the post-reionisation Universe. Such measurements will be performed by future radio telescopes such as for instance the Square WebMay 1, 2024 · The HI intensity mapping technique consists of making maps of the brightness temperature of the sky at different frequencies. Since no other emission lines appear at these radio frequencies, there is a unique relation between observed frequency and redshift, ( 1 + z ) ν = ν HI = c ∕ λ HI , with λ HI = 21 cm the rest-frame wavelength of ... portsmouth city auto auction
