Sentences with phrase «of a gravitational lens»

To understand the causes of those fine structures, the research team produced a sophisticated model of the gravitational lens.

By measuring the angle of bending, astronomers can calculate the mass of the gravitational lens (the greater the bend, the more massive the lens).

Artist's conception of gravitational lens arrangement that allowed astronomers to measure galaxy's magnetic field.

Video Simulation of the effects of the gravitational lens on the image of SDP.81.

Decades passed before astronomical technology verified that idea: It wasn't until 1979 that astronomers detected a real - life example of a gravitational lens in the double image of a quasar — side - by - side glimpses of a galaxy's blazing heart, resembling a pair of oncoming headlights.

To train the neural networks in what to look for, the researchers showed them about half a million simulated images of gravitational lenses for about a day.

But even through the galaxy cluster — size magnifying glass of a gravitational lens, Hubble can only see these early galaxies as dim smudges reddened by cosmic expansion.

Theoretically, the work is valid for any type of gravitational lens, but its practical applications are not yet clear.

Now, Readhead and his colleagues argue that they're seeing the blazar's black hole emit tiny burps of plasma, magnified hundreds of times by a new kind of gravitational lens.

Image of the gravitational lens RX J1131 - 1231 galaxy with the lens galaxy at the center and four lensed background quasars.

Jackson and colleagues used the Karl G. Jansky Very Large Array, in New Mexico, US, to study four examples of gravitational lens systems where the background quasar appears in a ring of four, distorted images.

However, the identification of gravitational lenses is often time - intensive, involving the sifting of large volumes of imaging or spectroscopic data to find few candidates.

General relativity has been experimentally verified by observations of gravitational lenses, the orbit of the planet Mercury, the dilation of time in Earth's gravitational field, and gravitational waves from merging black holes.

To make this observation, the team also enlisted the help of a gravitational lens, a galaxy - size magnifying glass, to reveal otherwise invisible detail.

Diagram of a gravitational lens.

The Einstein Cross — The European Space Agency's Faint Object Camera on board NASA's Hubble Space Telescope has provided astronomers with the most detailed image ever taken of the gravitational lens G2237 + 0305 — sometimes referred to as the Einstein Cross.

Researchers were able to study the quasar (seen above) in detail, thanks to the magnifying effect of a gravitational lens — a massive galaxy cluster in front of it — that caused it to appear brighter than it would have otherwise.

The model shows that a black hole with more than 300 million times the mass of the Sun darkens the central image by changing the effects of the gravitational lens.
