21cm Radiation: Really, Really Fine
21cm radiation results from the hyperfine splitting in the neutral
hydrogen atom. This very distinct form of radiation can be used to
map HI regions in our galaxy, and in the universe at large. As is so
often the case, the name can be a bit of a misnomer, as astronomers
are often observing the radiation redshifted far from a wavelength of
21 cm. Whatever the wavelength, by the time it reaches us here on
Earth, it's value to astronomy is undeniable with applications from
mapping the structure of our galaxy to investigating the epoch of
reionization.
