Mapping luminosity-redshift relationship to Lemaitre-Tolman-Bondi cosmology We derive a direct general map from the luminosity distance ${D}_{L}(z)$ to the inhomogeneous matter distribution $M(r)$ in the Lemaitre-Tolman-Bondi (LTB)... DJH Chung,AE Romano - 《Physical Review D》 被引量:...
distances and redshiftsThe Tully–Fisher relationship (TFR) has been shown to have a relatively small observed scatter of ±0.35 mag implying an intrinsic scatter < ±0.30 mag. However, when the TFR is calibrated from distances derived from the Hubble relation for field galaxies scatter is ...

3. What is the relationship between redshift and distance in cosmology? Redshift and distance are directly related in cosmology. The further away an object is, the higher its redshift will be. This is due to the expansion of the universe, which causes objects to appear to be moving away ...
the approximation of constant expansion rate fails, and the Hubble law becomes anon-linearintegral relationship dependent on the history of the expansion rate since the emission of the light from the source in question. Observations of the redshift-distance relationship can be used, then, to determ...
Technically, Hubble found the Hubble relation, a linear relationship between galaxy redshift and distance (see Fig. 1 for a reproduction of Hubble's original 1929 plot). Note that the horizontal axis is in terms of parsecs (pc), the preferred unit of distance outside the solar system. The...
We derive a direct general map from the luminosity distance D(z) to the inhomogeneous matter distribution M(r) in the Lemaitre-Tolman-Bondi (LTB) cosmology and compute several examples. One of our examples explicitly demonstrates that it is possible to tune the LTB cosmological solution to ...
Logical conditions use a three-valued Boolean logic where the null value represents an unknown relationship. The following table describes the results for logical conditions, where E1 and E2 represent expressions: E1 E2 E1 AND E2 E1 OR E2 NOT E2 TRUE TRUE TRUE TRUE FALSE TRUE FALSE FALSE ...

Evolution of the luminosity relations is allowed to the extent at which the cosmology deviates from this distance/redshift relation. (4) Theoretical explanations of the luminosity relations all base the relations on conservation of energy, speed of light, and other physics that do not evolve with...
