用redshift造句子，“redshift”造句

The universe as it appears today is redshift 0. Redshift 1 refers to when the universe was half its present age.

Spacetime must be somehow granular to tame the dubious infinite redshift.

As light from the most distant explosions travels toward Earth, it is stretched by the universe's expansion so that it appears red, a phenomenon known as redshift.

It's sort of pioneering in many ways, because doing this kind of detailed study of a galaxy at a very high redshift is extremely difficult.

The latest observations, which reach a redshift of about 2, are consistent with dark energy having been around in more or less its current form for the past 10 billion years.

The Doppler redshift and the cosmological redshift are governed by two distinct formulas.

The quasar lies at a redshift of 1.41.

"This galaxy is just beautiful," says Yuan. "Normally, galaxies at that redshift appear as blobs."

Astronomers can deduce the recession velocity of a supernova by measuring the redshift of the light from the galaxy in which it lies.

In addition the images of some of the lensed galaxies appear red - the large distance to these galaxies introduce redshift, which shifts their light to the red part of the spectrum.

The cosmological redshift is not a normal Doppler shift.

A decreased frequency is equivalent to a longer, or redder, wavelength. This is gravitational redshift.

A novel method for redshift determination and spectral line identification of celestial spectra is presented, which is based on the knowledge of feature spectral lines.

When Cowie and Lilly calculated the star formation rates in all the galaxies they observed, they came to the remarkable conclusion that the universe underwent a veritable baby boom at a redshift of about one.

The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see .

On the histograms of their redshift, optical luminosity and average optical X-ray spectral index, it is found that X-ray selected quasars are distributed at the low ends of plots of these parameters.

General relativity predicts that the wavelength of this light will be shifted by a small amount due to the galaxies' mass, in an effect called gravitational redshift.

The foreground galaxy lies at a redshift of 0.39.

With the Hubble Space Telescope it might be possible to find some galaxies up to redshift 10, but these objects are expected to be very rare and extremely faint.

Misunderstandings about the relation between redshift and velocity abound.
