Lensing in a sentence

There are two types of lensing: strong lensing produces multiple images or giant arcs near the cluster core, while weak lensing is observed as small shape distortions around the outer regions.

During a recent meeting of the board’s Operational Services Committee, board member Christine Lensing wanted to know if A Safe Place will offer counseling to people trying to leave gangs.

This is what is known as gravitational lensing.

It’s called gravitational lensing, and depending on your angle of approach, a dazzling halo could form around it.

The lensing makes the Firefly Sparkle appear as an arc.

To explain how gravitational lensing works, astronomers start with the analogy of a bowling ball placed on a foam mattress or trampoline.

The cinematography in a music video award went to Andrey Nikolaev for lensing an ironic Russian sendup of power and youth obsession in Aigel’s “You’re Born,” directed by Andžejs Gavrišs.

The larger smears are expected distortions due to gravitational lensing of the clusters, but there are also smaller distortions near the center of clusters, which the researchers believe are due to the presence of dark matter.

Astronomers often use gravitational lensing as a natural telescope, to great effect.

It kind of evolved that way and then Jaume and I came up with a lensing chart.

There’s more of an intimate feel, both to camera movement and to the close up lensing of those moments with each character.

A study of the gravitational lensing of this system suggests that the light emitted has been magnified by a factor of ~10.

By measuring the shapes and orientations of large numbers of distant galaxies, their orientations can be averaged to measure the shear of the lensing field in any region.

Dark matter distribution - weak gravitational lensing ( Hubble Space Telescope ).

Description Gravitational lensing - intervening galaxy modifies appearance of a galaxy far behind it (video; artist's concept).

Explanation in terms of space–time curvature seeAlso Simulated gravitational lensing (black hole going past a background galaxy).

Gravitational lensing observations of galaxy clusters allow direct estimates of the gravitational mass based on its effect on light coming from background galaxies, since large collections of matter (dark or otherwise) gravitationally deflect light.

It had some success explaining the rotational velocity curves of elliptical and dwarf elliptical galaxies that it was designed to match, but fails on galaxy cluster gravitational lensing.

More commonly, where the lensing mass is complex (such as a galaxy group or cluster ) and does not cause a spherical distortion of space–time, the source will resemble partial arcs scattered around the lens.

Note the gravitational lensing effect, which produces two enlarged but highly distorted views of the Cloud.
