cosmological redshift

The redshift resulting from the expansion of the Universe rather than from gravitational effects of intervening matter (see gravitational redshift) or from the motion of an intragalactic object away from the Solar System. See also cosmic scale factor.

cosmological redshift

The red shift that can be ascribed entirely to the general expansion of space-time initiated by the big bang.

In this world the gravitational potential is the same in any point and thus the cosmological redshift is favoured as a kinetic phenomenon of special relativity.
Lemaitre deduced the cosmological redshift on the basis of Einstein's field equation.
under the assumption that the cosmological redshift is a result of the Doppler effect in an expanding space.
The cosmological redshift of a remote galaxy is figured from this simple expression:
Perhaps with the Doppler interpretation of the cosmological redshift reconsidered -- and rejected -- we can at last embrace the essential beauty and mystery of cosmic expansion as originally envisioned by its discoverers.
There is no need for expansion of space and its cosmological redshift to explain the SNe1a data.
Distant redshifted SNe1a light sources from the Universe that are usually interpreted as cosmological redshifts are shown to be universal gravitational redshifts seen by all observers in the quantum celestial mechanics (QCM) approach to cosmology.
His theories regarding quantized cosmological redshifts of galaxies are starting to be accepted, albeit grudgingly.
These maps have generally depended on calculating galaxies' 3-D locations based on their cosmological redshifts.
On the basis of this test, we conclude that the dichotomous cosmology provides an accurate description of the physics underlying cosmological redshifts.
Two approaches are available for converting the redshifts from observed galaxies into LTDs, one based on cosmological redshifts and the other one on dopplerian redshifts.
The difference between dopplerian and cosmological redshifts is discussed by Bedran [2].
