redshift Definition
red·shift (red′s̸hift′)
noun
Astron. the shift of spectral lines toward the longer wavelengths and lower frequencies at the red end of the spectrum in a luminous celestial body, indicating that the light source is moving rapidly away from the observer: thought to be a Doppler effect explaining an expanding universe, or the result of a strong gravitational field

redshift Usage Examples
Preposition: of
- quasar: Their spectra also have the same large redshift of the quasars in the cluster.
- galaxy: With this new direct determination of distance, a comparison can be made with that inferred from the redshift of the remote galaxies.
- object: The recording of the spectrum and redshift of this object is noteworthy in itself.
Converse of object
- give: This allows to estimate the infrared photon field up to the given redshift of the source.
- have: Their spectra also have the same large redshift of the quasars in the cluster.
- measure: If the GRB is at a distance greater than z ~ 1, the filtered observations will also measure the redshift of the GRB.
Adjective modifier
- photometric: We estimate a photometric redshift of for this galaxy, using the methods of Mobasher et al.
- spectroscopic: UVOT REDSHIFT If grism data are available, can a spectroscopic redshift be obtained?
- gravitational: In particular, the gravitational redshift causes the emission to be skewed to low energies: the line exhibits a " red wing " .
- high: Our best fit model has a flatter bright end slope at high redshift than at low redshift.
- low: Our best fit model has a flatter bright end slope at high redshift than at low redshift.
- same: Three of these four galaxies show nearly the same redshift, indicating that they reside at the same distance from us.
Modifies a noun
- quasar: The low and high redshift quasars are found very similar in their emission characteristics, although differences exist.
- galaxy: I have also done some notable research on active galaxies and searches for high redshift galaxies and active galactic nuclei.
- survey: Many redshift surveys are being undertaken to gain an understanding of the geometry of the Universe in three spatial dimensions.
- distribution: These are shown in Figure 9 together with the redshift distribution from the PRR model.
- object: An alternative strategy would be the targeted search for galaxies clustered around known high redshift objects ( radio galaxies and QSOs ).
- value: A redshift value of zero means that there is no measurement.
