NOUN
- (astronomy) a shift in the spectra of very distant galaxies toward longer wavelengths (toward the red end of the spectrum); generally interpreted as evidence that the universe is expanding
How To Use redshift In A Sentence
- Figure 2 shows the time variation of the flux densities and velocities at peak intensities for the strongest four redshifted components at.
- Conversely, to achieve a certain redshift in such a universe, the light has to travel a greater distance than it would in a uniformly expanding universe, in which case the supernova has to be farther away and therefore appear dimmer. Archive 2009-03-01
- For the large angular-scale fluctuations, the denser regions redshifted the light climbing out of those regions, and therefore produce cooler spots in the CMBR; in contrast, for the small angular-scale fluctuations, denser regions were regions where the plasma was hotter, hence these denser regions produce hotter spots in the CMBR.

- Their painstaking work reveals what many astronomers suspected but, until now, could never prove: the redshift desert is a mirage.
- In this paper a statistical investigation has been made on the redshift-magnitude relation of quasars with radio components structure.
- The advantages of this new method is that it goes to high redshift, that is, it looks at the expansion history of the Universe from 1. 7-6.3 in redshift. Evolving dark energy?
- In order to be visible at all at the huge distances implied by their redshifts, quasars must produce prodigious amounts of energy.
- It would seem easy to disprove this by observation, since light passing close to the sun or some other star would be neutralized if it is blueshifted falling and redshifted by an equal amount climbing out, but if the light is being stretched out as it fell in and stretched as it climbed out, there would be an overall redshift from this passage. A Dark, Misleading Force
- In excited atoms, energy radiated as photons eventually leaks into the vast interstellar spaces and redshifts away.
- The redshift in the absorption spectrum reflects electronic interactions between the porphyrin and the melanins.
