	Redshift - Wikipedia, the free encyclopedia
		This redshift phenomenon was first predicted and observed in the nineteenth century as scientists began to consider the dynamical implications of the wave-nature of light.
		Most famously, redshifts are observed in the spectra from distant galaxies, quasars, and intergalactic gas clouds to increase proportionally with the distance to the object.
		Redshift (and blueshift) may be characterized by the relative difference between the observed and emitted wavelengths (or frequency) of an object.

	redshift (Site not responding. Last check: 2007-10-22)
		The measure of this redshifting of light is given by the quantity z, which is defined as the change in wavelength of a given spectral line divided by the laboratory standard wavelength for that same spectral line.
		Redshift is determined by observing spectral lines of specific elements in a source, and noting how far they have moved from their laboratory (rest frame) wavelength.
		The absence of expansion redshifts in a static-space-time universe suggests a reevaluation of the present cosmology is needed.

	Astronomical Redshift
		Astronomical redshift is the lengthening of emitted radiation as detected by observers.
		Cosmological redshift is caused by the relativistic expansion of the universe, as quantified by the Hubble constant, H
		These redshifts are a result of the stretching of space time, as postulated by general relativity, and not by radial motion.

	Redshifts and the Hubble Law
		Central to Arp's disagreement with accepted theory is the fact that redshifts of extragalactic objects are not caused by velocity alone.
		There are numerous examples of this in quasars with redshifts approaching the velocity of light, of peculiar galaxies with redshifts from 1,000 to 30,000 km/sec and in more normal, companion galaxies in the range of a few hundred km/sec.
		This means that, for example, an atom of hydrogen in a high redshifted object, which makes a given transition from one energy state to the other, must emit or absorb a photon of lesser energy than the same atom would in a lower redshifted one.

	A New Non-Doppler Redshift
		The mere examination of a recent catalog of objects having very large redshifts shows that among 109 quasi-stellar objects, in which both absorption and emission lines could be measured, the value of the absorption redshift in a given object, is always different from the one measured in emission for the same object.
		It may at least be perceived that the redshift is emission should, in general, be different from that in absorption, and also be influenced by the energy of the quantum states that characterize the absorption medium.
		In all 109 cases, the emission redshift is different from the absorption shift (for one and the same object).

	Halton Arp's discoveries about redshift
		Arp has photographs of many pairs of high redshift quasars that are symmetrically located on either side of what he suggests are their parent, low redshift galaxies.
		Both have the same intrinsic redshift value and their velocity redshift values are equal in magnitude but opposite in sign (one is approaching us and one is receding).
		Instead of nominating him for a prize (and simultaneously reexamining their assumption that "redshift equals distance"), Arp was (and continues to be) systematically denied publication of his results and refused telescope time.

	Doppler Shift (Site not responding. Last check: 2007-10-22)
		Observers looking at an object that is moving away from them see light that has a longer wavelength than it had when it was emitted (a redshift), while observers looking at an approaching source see light that is shifted to shorter wavelength (a blueshift).
		When z is larger than 1 then cz is faster than the speed of light and, while recession velocities faster than light are allowed, this approximation using cz as the recession velocity of an object is no longer valid.
		Thus for the largest known redshift of z=6.3, the recession velocity is not 6.3*c = 1,890,000 km/sec.

	Redshift of Spectral lines in the Sun's Chromosphere
		calculated above, the redshift of the iron lines observed is compatible with the calculation that the pressure effect starts to appear at about the solar altitude of 277 km.
		It is clear that the velocity of such a mass motion must be adjusted in order to compensate exactly for the redshift on the center of the disk, and also be adjusted exactly to the relativistic value on the limb, since any radial motion has no effect on the limb as seen from Earth.
		Furthermore, the redshift at the center of the disk is adjusted with a proper choice of the parameters E/kT.

	Space Guide - Redshift
		Redshift and the Doppler Effect are often discussed together as one helps to explain the other.
		Therefore if a visible object is redshifted, it generates absorption lines in the spectrum that appear to be at the lower (or red) end of the visible spectrum than would be expected if the object were stationary.
		Furthermore, Edwin Hubble plotted the redshift recession velocities of galaxies and noted that the further away the galaxies were, the higher were their redshifts.

	ESA Science & Technology: Cosmology
		The degree of redshift is related to the velocity of recession, or how fast away from us the galaxy is moving.
		In 1929 astronomer Edwin Hubble produced a paper that plotted the relationship between the velocity of recession and the distance.
		This phenomenon is described as the Doppler redshift.

	The SF Site Featured Review: Redshift
		While here in Redshift, we are given, for example, Ardath Mayhar's "Fungi," a nice enough story that could have been published without a word changed in any early 50s magazine -- and indeed, very similar stories, with similar themes, were published in early 50s magazines.
		Sarrantonio's further claim, that his anthology is the best original anthology of the past 25 years, is at least defensible from the point of view of his understandable bias -- but speaking as a reviewer, I can't endorse that claim either, though this book is a fine collection of stories.
		So, even if Redshift doesn't live up to the editor's hype, and even if it features quite a few stories that aren't really up to snuff, it is a long book, and the best stories in it are certainly worth the price of the book, and worth your reading attention.

		Using early period Tangerine Dream, Klaus Schulze, Neu, Kraftwerk etc as a starting point, Redshift's music is as hard to describe as it is to categorise.
		With each current album the band are continuing to push forward the boundaries of electronic music with recordings that should please fans of the genre as well as finding a new audience for a style of music which has been largely overlooked in the current flurry of media attention for dance based music.
		The result is a truly unique sound, with a warmth and depth that simply can't be found in the current crop of chart music.

	On the Quantization of the Red-Shifted Light from Distant Galaxies
		Edwin Hubble showed in 1929 that the more distant the galaxy, the larger this "redshift." Astronomers traditionally have interpreted the redshift as a Doppler shift induced as the galaxies recede from us within an expanding universe.
		The galaxies in the Coma Cluster, for example, seemed to arrange themselves along sloping bands in a redshift v.s.
		First revealed in the Coma Cluster redshift vs. brightness diagram, it appeared as if redshifts were in some way analogous to the energy levels within atoms.

	Redshift Surveys of the Local Universe
		The redshift completeness of the survey is currently 91% and rising, as data quality and reduction methods are refined.
		Figure 2 shows both the 2dF galaxy and QSO surveys on a single redshift cone diagram; the density of sampling of the galaxies at low redshift is complemented by the sparser QSO sample reaching out to beyond z=2.2.
		This would build on existing redshift catalogues and, in the north, fill in the missing redshifts with the 1.3m at FLWO used for the CfA redshift surveys.

	Sloan Digital Sky Survey
		Redshift is the amount by which light is shifted toward the red end of an object's spectrum by the expansion of the universe.
		Astronomers use redshift as a measure of the distance of celestial objects: the higher the redshift, the greater the distance and the younger the universe when the light was emitted.
		Many said long-held expectations were already being confirmed that the project will readily generate masses of detailed data that will not only chart the skies, but also present a magnificent panorama of the large-scale structure of the universe.
