Web3. mar 2016 · When astronomers observe distant galaxies, the entire spectrum is redshifted, so all features appear at a wavelength redder than would be expected. The ultraviolet drop is such a dramatic feature that it can be readily identified and used to obtain the redshift of a galaxy, and therefore its distance. The galaxy GN-z11 is such a galaxy.
