“redshift”可以造什么句，redshift造句

The cosmological redshift is not a normal Doppler shift.

The quasar lies at a redshift of 1.41.

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

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

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

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.

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.

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.

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.

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.

Misunderstandings about the relation between redshift and velocity abound.

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

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.

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.

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.

The foreground galaxy lies at a redshift of 0.39.

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

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

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.

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