Web8 de nov. de 2024 · The relationship depends on a ( t) and the curvature k. In principle, if we measure distances and redshifts for objects at a variety of distances we could then infer a ( t) and k. The general relationship between redshift and luminosity distance is contained in these equations: (8.6) c ∫ a e 1 d a a 2 H = ∫ 0 d d r 1 − k r 2. WebIn terms of cosmography, the cosmological redshift is directly related to the scale factor a (t), or the ``size'' of the Universe. For an object at redshift z (11) where a (t 0) is the size of the Universe at the time the light from the object is observed, and a (t e) is the size at the time it was emitted.
