Sentence examples for redshift from inspiring English sources
The word "redshift" is correct and can be used in written English
You can use this word to describe the phenomenon where the light emitted by distant galaxies is shifted towards the red end of the light spectrum, due to the Doppler Effect which is caused by the Universe's expansion. Here is an example sentence: "The redshift of distant galaxies suggests that the universe is expanding."
noun
A change in the wavelength of light, in which the wavelength is longer than when it was emitted at the source.
The rate at which stars and galaxies are moving away from Earth, meanwhile, can be worked out from their redshift.
But Dr Wetterich's latest paper, published on arXiv, an online repository, attempts to back it up.In Dr Wetterich's picture of the cosmos the redshift others attribute to expansion is, rather, the result of the universe putting on weight.
In addition, the speed at which an object such as a star or galaxy is moving away from Earth, because of the expansion of the universe, can be worked out from its redshift.
The latter is done by measuring the so-called redshift of their light.
And that, plus a measurement of the quasar's redshift, produces the Hubble constant in one shot, without all the messy intermediate steps that standard candles require.
The Dark Energy Camera, which lacks a spectrograph, has to rely on other telescopes which do have them to make its redshift measurements for it.
The recession speed, meanwhile, reveals itself through the so-called "redshift".
When Hubble turned to the problem of the distance-redshift relationship, he soon superseded Slipher's work.
Hubble's paper led to a rapid acceptance of the distance-redshift (or distance-velocity) relation in the astronomical community, and this relationship is known as "Hubble's law," although, as discussed above, it had been several times anticipated.
It also has more bells and whistles than the Dark Energy Camera; specifically, it has an integral spectrograph, for working out redshifts.Redshifts are one of astronomy's most important sources of information.
In other words, the supernovae were farther away than their redshifts indicated they should be, based on the existing model of the universe.
