In this formula, the speed of light c and the hubble constant h0 are known constants.As of may 2024, does the us state of georgia allow water to be available to you while you wait in line to vote in an election?
The comoving volume within redshift z is 1140.389 gpc 3.It is not the distance of the celestial body when the light was emitted since it was shorter, nor the actual distanceThe reverse operation is also possible, though not always as simple.
By substituting the value of the recessional velocity from the first equation into the second equation, we get:To convert a very large distance to a redshift it might be necessary to specify a large enough zmax value.
1 gly = 1,000,000,000 light years or 9.461*10 26 cm.Ω m h 0 km/s/mpc redshift <=> scale factor parsecs:The comoving radial distance, which goes into hubble's law, is 6481.3 mpc or 21.139 gly.
This carries on into the angular size and luminosity.The angular size distance d a is 1620.3 mpc or 5.2846 gly.
Then rearrange the terms of the redshift equation to get v = z c.For comoving distance this makes no difference, but for zeff it tells us the redshift the object z1 is observing the object at z2 for the age of the universe we observe z1 to be at (e.g.Cosmological calculator for the flat universe by nick gnedin input either one:
