WebRedshift and Energy Conservation - 4 - Consider first the limited case where j =p ¶.The energy flux measured by the observer is reduced by a factor (1+z)4 in comparison with equation (3) (see, for example, Misner, Thorne and Wheeler1, sections 22.6 and 29.4).The four powers of (1+z) include a combination of local and global effects. WebMeasuring the galaxy's redshift is one step toward determining its distance. The next step is using the Hubble relation. The Hubble relation is a (locally) linear correlation between …
Web22 feb. 2024 · The "redshift" measurements that Hubble used to determine his law are based on looking at the spectrum of distant galaxies. That is, splitting the light coming from the object in its constituent colors (e.g. by passing it through a prism). If you look at such a spectrum, you will notice that certain lines (colors) are missing. Web1 sep. 2024 · you measure a redshift, you know Hubble’s law and how the expanding Universe works, so you can assign a distance to each object, and create a map of the …
