Sentences with phrase «galaxies by its gravitational lensing»

A newly released image from NASA Hubble telescope reveals that a huge cluster of galaxies called Abell 370, has an array of galaxies guarding it and is useful in studying far - flung galaxies by its gravitational lensing property.

Some are using the theory to predict the warped appearance of galaxies by gravitational lensing.

Not exact matches

Fritz Zwicky used it for the first time to declare the observed phenomena consistent with dark matter observations as the rotational speeds of galaxies and orbital velocities of galaxies in clusters, gravitational lensing of background objects by galaxy clusters such as the Bullet cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies.

The image showed that the galaxy had an arc shape characteristic of gravitational lensing by an intervening galaxy, Graham reported last month at a meeting of the American Astronomical Society in Pittsburgh.

However, through the phenomenon known as «gravitational lensing,» a massive, foreground cluster of galaxies acts as a natural «zoom lens» in space by magnifying and stretching images of far more distant background galaxies.

If a distant galaxy were lined up right behind one more close by, this warping would bend and magnify the faraway galaxy's image, a phenomenon now called gravitational lensing.

Gravitational lensing shows that two galaxy clusters are connected by a filament of dark matter.

This is a subtle variant of weak gravitational lensing, in which the light emitted from distant galaxies is slightly warped by the gravitational effect of large amounts of matter, such as galaxy clusters.

Another experiment there, the South Pole Telescope, reported finding B - mode polarization last year, although the signal it saw was at a different angular scale across the sky and was clearly due to the known process of gravitational lensing (a warping of light caused by massive objects) of the CMB by large galaxies, rather than the primordial gravitational waves seen here.

Observations by the NASA / ESA Hubble Space Telescope have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the Universe.

According to Gould and Villumsen, the gravitational lensing induced by these nearby structures should show up in a large survey of galaxies being conducted by James Gunn at Princeton University in New Jersey and his colleagues.

The best way to work out where the dark matter lies is through gravitational lensing — the distortion of the Universe's fabric by gravity, which deflects the light coming from distant galaxies far beyond the dark matter.

In addition, the gravitational lensing of quasars by distant galaxies is only possible if the lensed quasars are farther away than the galaxy bending the quasar's light.

The study of the gravitational lensing is detailed in the paper «ALMA observations of strongly lensed dusty star - forming galaxies», by Y. Hezaveh et al., also in the Astrophysical Journal.

The scientists used the fact that images of faraway galaxies get slightly distorted by the gravity of galaxies in the foreground — an effect known as weak gravitational lensing.

NASA said the background galaxy has been magnified, distorted and multiply imaged by the gravity of the galaxy cluster in a process known as gravitational lensing.

These cosmic lenses are created by massive structures like galaxies and galaxy clusters, which deflect the light from objects behind them due to their strong gravity — an effect, called gravitational lensing.

Gravitational lensing by the giant cluster brightened the light from the newfound galaxy, known as MACS 1149 - JD, some 15 times.

Astronomers can see this individual star because its light has been highly magnified by an intervening galaxy cluster through a process called gravitational lensing, said Liliya Williams, University professor in the Minnesota Institute for Astrophysics.

In the 1990s, astrophysicists used gravitational lensing to see far - away galaxies, but the technique has since been neglected by many scientists, Kelly said.

The ultra-deep images of galaxy clusters are revealing the faintest galaxies ever studied, magnified by gravitational lensing.

Once in grad school at Johns Hopkins, my advisor Narciso Benitez started me working on mapping dark matter in galaxy clusters by modeling gravitational lensing, and measuring distances to galaxies in new Hubble ACS images, including the UDF.

Astronomers inferred its location by analyzing the effect of gravitational lensing, where light from galaxies behind Abell 1689 is distorted by intervening matter within the cluster.
