A long time ago, in a galaxy far far away…so the story goes

WebIt can be measured by observing the wavelength shifts of spectral lines emitted by the object, known as the object's cosmological redshift. Application to cosmology [ edit ] Hubble's law is the relationship between a galaxy's distance and its recessional velocity, which is approximately linear for galaxies at distances of up to a few hundred … WebI organized this review at the highest level by redshift. This is useful for two reasons. First, star formation and galaxy properties at redshifts above unity differ significantly from those in the local universe. The global star formation rate (SFR) peaked at z ∼ 1.9 (e.g., ) and gas mass fraction increases with increasing redshift (e.g., ).
