WebIn cosmology, intensity mapping is an observational technique for surveying the large-scale structure of the universe by using the integrated radio emission from unresolved gas … WebA different way to trace the Universe's large-scale structure is by detecting the 21cm emission from cosmic neutral hydrogen using the intensity mapping technique. The idea is to carry out a low angular-resolution survey where the emission from many unresolved galaxies and HI blobs is measured. The method is illustrated in the below image. 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 ... small german shorthair pointers
