Web16. apr 2016 · The redshift of very distant galaxies is mainly due to the expansion of space whilst the light has been travelling towards us. The basic relationship (at non-relativistic speeds) is that v = H 0 d where v is the velocity implied by the redshift and d is the distance. The constant of proportionality H 0 ∼ 70 km/s per Mpc. Web23. dec 2016 · The amount of broadening is exactly in proportion to the amount of redshift $(1+z)$ observed in the spectra of the same supernovae. i.e the cosmological time dilation works as expected for an expanding universe, see for example Blondin et al. (2008). A "gradual redshifting" of light as it travelled a distance cannot explain this time dilation. cx8 納車期間

Answers Answer from: kyramks421 taurus pneu wikipédiaWebIf the redshift is z, then the wavelength of light you observe is at a wavelength that is 1 + z times longer than the wavelength emitted in the frame of reference of the galaxy. In this case z = 0.373, so when you observe light centered on say the 3.4 micron band, then the light was emitted at a wavelength of 3.4/1.373 microns.
