Sentences with phrase «act as a gravitational lens»

On the probability of detecting nebulae which act as gravitational lenses.

Astronomer Tiantian Yuan at Swinburne University of Technology in Melbourne, Australia and colleagues found the new record - holder thanks to a closer cluster of galaxies, which acted as a gravitational lens that helped astronomers produce two magnified images of A1689B11 (SN: 3/10/12, p. 4).

Its discoverers proposed that a galaxy cluster acted as a gravitational lens, warping space - time and, in effect, focusing the light towards Earth.

A chance to get a close look is coming soon: Kervella's team mapped out the system's trajectory and found that in a decade, Alpha Centauri A will pass in front of a more distant star and act as a gravitational lens, distorting the light of the star behind it.

The wobbling of the BCGs could only be analysed as the galaxy clusters studied also act as gravitational lenses.

The image of this quasar is split into four by a massive galaxy acting as a gravitational lens.

This image combines views from the Keck II telescope using adaptive optics and Hubble to show a foreground galaxy that is acting as the gravitational lens.

This is made up largely of dark matter and is so massive that it bends light around itself and acts as a gravitational lens millions of light years in diameter.

Not exact matches

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.

The H0LiCOW astronomers measured the Hubble constant by exploiting massive galaxies that act as «gravitational lenses,» bending light from a yet more distant object.

In the 1930s Einstein predicted that a mass distribution, such as a galaxy, could act as a gravitational «lens,» not only bending light but also distorting images of objects lying beyond the gravitating mass.

Occasionally, when the stars are aligned just right, this warping of the fabric of the universe results in a phenomenon known as gravitational lensing, wherein the strong gravitational field of a foreground object acts as a lens that «bends» light from an object in the background and allows scientists to catch a glimpse of what might otherwise have remained invisible.

... discerned through the phenomenon of gravitational lensing — matter acting as a lens by bending space and distorting the passage of background light.

Therefore, the cluster acts as a large gravitational lens, much like an optical lens (see How Light Works).
