red shift

or red·shift (rĕd′shĭft′)
n.
An increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect.

[From the fact that the longer wavelengths of light are at the red end of the visible spectrum.]

red shift

An increase in the wavelength of radiation emitted by a receding celestial body as a result of the Doppler effect. Objects appear reddish because the longer wavelengths of light are at the red end of the visible spectrum. Compare blue shift. See Note at Doppler effect.

red shift

An effect by which the faster an object moves away from Earth the redder its light spectrum becomes.

Because red shifts were the infrared effects identified in these bonds, the variations of the s- and p-orbitals should provide insights in this regard.
For high quality Si[O.sub.x] thin films, a PL peak was reported to have red shifts with decreasing oxygen concentration [16] and/or increasing the annealing temperature [17].
In addition, with the increasing of size of center bar of the lattice, center frequency of the new transmission dip hardly moves, but the original transmission dip red shifts obviously accompanied by the increase of full width at half maximum.
All of solvatochromic spectral measurement have been summarized as follows: The p-TNC4 shows red shifts in DMSO, DMF and MeCN with respect to CF and/or DCM which can be ascribed to the (pi)-(pi) and n-(pi) transitions arise as a result of solvents with different polarities.
The prevalence of red shifts led to the belief that heating is taking place high in the sun's atmosphere and leading to the evaporation of material from near the surface into the atmosphere that then flows back down as it cools.
The intended method was the same as astronomers had been using from the ground: measure the distances of galaxies by the brightnesses and periods of their Cepheid variable stars, then match these distances to the galaxies' observed red shifts (how fast they're receding from us).
"However, only when the James Webb Space Telescope is launched will these first phases of galaxy build-up between (red shifts of 15 and red shifts of 10) be revealed," they wrote.
To implement the Planck scale successfully in cosmology, to develop a unified model of cosmology and to obtain the value of present Hubble's constant (without considering the cosmic red shifts), starting from the Planck scale it is assumed that at any time t: (1) The universe can be treated as a rotating and growing black hole; (2) With increasing mass and decreasing angular velocity universe always rotates with speed of light; (3A) Without cosmic rotation there is no "cosmic temperature"; (3B) Cosmic temperature follows Hawking black hole temperature formula where mass is equal to the geometric mean of Planck mass MP and cosmic mass Mt; (4) Rate of decrease in CMBR temperature is a measure of cosmic rate of expansion.
These blue and red shifts broaden the spectrum of X rays emitted from the iron atoms in the accretion disk.
New instruments and computerized techniques made it possible to detect galaxies with red shifts (see 1925) greater than any previously seen; greater even than those of quasars.
