| Previous attempts to measure a neutron star's redshift focused on a star with an enormous magnetic field. |
|
| This determination assumes the variation of the redshift is indeed a Doppler effect due to motion of the star. |
|
| For this reason, the principal tool of cosmography has become the redshift survey. |
|
| He has observed high redshift companion galaxies connected to low redshift spiral galaxies. |
|
| The redshift in the absorption spectrum reflects electronic interactions between the porphyrin and the melanins. |
|
| Thus there can be no redshift due to the Compton effect unless there is a change in the direction of propagation. |
|
| The spacing between successive lines is even reduced by the redshift, making the search more easy. |
|
| The recession velocity is relatively easy to determine: we can measure the so-called redshift of the light from the galaxy. |
|
| Molecular lines in the millimeter domain are one of the best mean to find the redshift, and therefore the distance and nature of such an object. |
|
| His theory is sophisticated and appeals to a gravitational and relativistic redshift caused by vacuum gravity repulsion. |
|
| This cosmology has the merit of explaining quantized redshift, which most present cosmologies fail to explain. |
|
| The rate at which stars and galaxies are moving away from Earth, meanwhile, can be worked out from their redshift. |
|
| The Dark Energy Camera, which lacks a spectrograph, has to rely on other telescopes which do have them to make its redshift measurements for it. |
|
| The greater the speed of movement, the greater the redshift, the further away the object will be. |
|
| Evidence, such as quantized redshift, has been offered as strong support that the Milky Way exists at the center of the universe. |
|
| The confirmation of the distances from such weak objects is an enormous challenge which can only be addressed by the spectroscopy on large ground-based telescopes, by measuring the redshift of the light of the galaxy. |
|
| Calculating the work done by the mass-radiation interaction on a photon, we derived the Einsteinian gravitational redshift. |
|
| And that, plus a measurement of the quasar's redshift, produces the Hubble constant in one shot, without all the messy intermediate steps that standard candles require. |
|
| The latter is done by measuring the so-called redshift of their light. |
|
| In effect we consider that the intrinsic redshift quantization could be interpreted as result of Hall effect in rotating frame. |
|
|
|
| Despite the acceptance of the Doppler redshift described by Hubble's law, there are problems with this model. |
|
| In addition, the speed at which an object such as a star or galaxy is moving away from Earth, because of the expansion of the universe, can be worked out from its redshift. |
|
| The team found its redshift, and therefore its distance, by methodically scanning the millimeter band to detect molecular lines, and in particular the CO lines. |
|
| It will search for the cold cosmic dust and line transitions from many molecules in a considerable number of objects, from quasars at large redshift to protoplanetary disks in regions of star formation. |
|
| The gravitational redshift also affects other sorts of radiation, such as radio waves. |
|
| At this stage, they made hypotheses about which CO line had been detected, and inferred what was the optimal tuning at higher frequency to confirm and definitely determine the redshift. |
|
| Our rationale was to slice a galactic survey into small redshift buckets. |
|
| The evidence that is the most difficult to explain away is the quantization of the cosmological redshift and the non-Doppler nature of quasar redshifts. |
|
| Their limits on anomalies in the physics of electrons that produce deviations from Einstein's gravitational redshift are 160 times better than previous experimental limits. |
|
| Known as gravitational redshift, the effect is caused by the black hole's powerful gravity, which slows time and causes light waves to lose energy. |
|
| Is it absurd to imagine that they might be slightly stretched or compressed as well, that the cosmological redshift might act differently on different wavelengths? |
|
| Redshift results from the Doppler effect, the same phenomenon that causes the siren on a fire truck to drop in pitch as the truck passes. |
|
| However, that's exactly how long a team of astronomers took in creating 2MASS Redshift Survey, a map of the universe. |
|
| Cosmological Redshift Interpreted as Gravitational Redshift. |
