Dec 23,  · Astronomers use gravitational microlensing to detect planets around other stars. The foreground star acts as a lens for a background star. As the star brightens up, you can detect further. Principles of Gravitational Lensing by Arthur B. Congdon, , available at Book Depository with free delivery worldwide. However, it is not as rare as you might expect because a second consequence of lensing is the fact that the quasar light is amplified. A gravitational lens will magnify light just as an optical lens will. Lensing therefore makes a quasar brighter than it would have been in the absence of a foreground galaxy. The phenomenon at the root of gravitational lensing is the deflection of light by gravitational fields predicted by Einstein's general relativity, in the weak-field limit. The deflection has well-known observable effects, such as multiple images, magnification of images, and time delays for propagation of light along the paths forming different images.

The effect of gravitational lensing also allowed a first step towards revealing the mystery of the dark energy. As gravitational lenses function as magnification glasses it is possible to use them to study distant galaxies from the early Universe, which otherwise would be impossible to see.

Gravitational Microlensing can be thought of as a version of strong gravitational lensing in which the image separation is too small to be resolved. Multiple images are formed, but their typical separation – Δθ ≈ 2 θE – is far below the limiting resolution determined by observational constraints.

We will start from the basics of the lensing .ascensionproducers.com Introduction Gravitational lensing is a very resourceful phenomenon that widely used in astronomy measurement.

It contains many aspects of which the strong, weak, and microlensing are well established by observable evidence. The weak gravitational lensing .A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the ascensionproducers.com effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity.
