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.

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.

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.
-
Whereas the effect of the redshift is to multiply the wavelength of every line in the spectrum by the name number, 1 + z, any variation in only changes the relative separation between the lines in the doublet.
-
Light as measured by an observer on the surface of a gravitating body would be blueshifted (compressed), while it is redshifted as measured by an observer watchiing photons emitted from the surface of a gravitating body.

Edwin Hubble observed and measured the departure of galaxies using a technique known as the redshift in physics.

When we perform a series of transformations into orthonormal frames at a series of points along the path, and the redshift is still exactly the same, and we go “ooooh look, now we have a series of Doppler shifts along the path”.

Infrared astronomy is traditionally described as focusing on the "old, cold and dusty" - that is, the redshifted light from ancient galaxies on the edge of the observable universe, cool objects such as brown dwarfs that shine only in infrared wavelengths, and infant stars and planets still wrapped in shrouds of dust. launched last May, is the most sensitive far-infrared telescope in operation.

If the light had been stretched, or 'redshifted', through the Doppler effect - the same distorting effect that causes an ambulance siren to rise in pitch when approaching or drop as it recedes - it could only mean one thing: everything in the universe was hurtling away from our humble Milky Way, and the further away it was, the faster it fled.

The first is to detect molecules such as CO (carbon monoxide) in galaxies up to redshift (z) of 3 (that's when the universe was just 2 billion years old!) in under 24 hours of observation.

The acceleration of the Universe can be seen in the redshifts of distant supernovae.

The stretching makes visible light look redder, which is known as the redshift.

Previous attempts to measure a neutron star's redshift focused on a star with an enormous magnetic field.

Lastly: I believe that despite this level of detail, this is fundamentally hoi polloi fiction redshifted or, to take our cue from political notation, blueshifted in the direction of complexity, without being, in itself, for the most part, complex.

The wavelengths of the radio waves emitted by the pulsar are lengthened as a result of the effects of the gravitational field of the companion star (gravitational redshift).
-
Light traveling a given distance is redshifted by less than it would be if the whole universe expanded at our local rate.

In both cases the galaxy is at a much lower redshift than the associated quasars, and is often disturbed in form or unusually active in showing starburst activity or in producing considerable radio emission.
-
In the case of HAT-P-7b the effect was reversed – that is, the redshifted light appeared bluer, then the blueshifted light appeared redder, making it apparent that the orbit of the planet was not in the same direction of that of HAT-P-7.

Astronomers often express the amount of redshift, the fractional change of wavelength, as a dimensionless number, z.
-
In planets with a prograde orbit, their transit in front of the star blocks the blue shifting of the light from the star first, then blocks the redshift of the light, making the star appear to move more that it actually is.

At least we are able to deduce a long history, geologically and evolutionarily on Earth, astrophysically with the age of stars and cosmologically with redshift and Hubble distance.

The Keck 10-m telescope in Hawaii, the 6. 5-m Magellan telescope in Chile, and the MMT telescope in Arizona rapidly focused on the new star, revealing that the wavelengths of light emitted from the supernova were stretched or 'redshifted' by 80 percent due to the expansion of the universe.

Whether this would explain all of the redshift is another matter, but it would seem to explain redshift as having other possible causes then only recession.
