Introduction to Gravitational Lensing B1938+666 is another multiple image lens, and was discovered in JVAS (Jodrell VLA Astrometric Sur vey). This is a survey of flat spectrum radio sources designed to identify gravitational lens candidates. HST observations show an Einstein ring in IR. The lens redshift is 0.878, but the source redshift is not yet known (IR spectroscopy required). Gravitational Lensing Basics Gravitational Lensing Gravitational lensing, which is the de°ection of light by gravitational flelds and the resulting efiect on images, is widely useful in cosmology and, at the same time, a source of irreducible uncertainty in certain measurements. Here we discuss the basics, followed by some real world complications and applications. FileGets Download Gravitational Lensing Software latest ... The characteristics of the gravitationally lensed image depend upon the alignment of the observer, the lens and the background object. If the alignment is perfect, the resulting image is an Einstein Ring. With this program, one can draw images to see the effect of gravitational lensing. Gravitational Lensing for Cosmology | SpringerLink The understanding of the formation of the large scale structures of the Universe is a fundamental problem of cosmology because of its close links to the physics of the early Universe. The... Gravitational Lensing for Cosmology | SpringerLink A galactic gravitational lens as the ultimate astronomical ... When a galaxy acts as a gravitational lens it behaves more like a raindrop deflecting sunlight than like a true lens. The images formed by a galaxy exist as directions of incidence of rays on the ...

Gravitational Lenses | SpringerLink Gravitational lenses are becoming a precious mean of probing the matter distribution in the Universe. From the search of matter in the Galactic halo to the study of the large scale structures of the Universe, the gravitational lens effects offer a unique alternative to light surveys and are now widely used. The phenomenon of gravitational lenses Eniscuola The phenomenon of gravitational lenses If we look carefully at the image taken with the Hubble Space Telescope, of the Galaxy Cluster Abell 2218 in the constellation of the Dragon, a few strange luminous arcs may be observed. What are these curious objects? Do luminous bodies with this strange shape exist in the Universe?

Magnification with a Gravitational Lens? One of the most distant observed objects in the universe, 13.4 billion light years, was observed with the help of the gravitational lens effect. The experimenters report an effective magnification of about 30, which allowed them to observe an object which would otherwise have been undetectable. Quasars hyperphysics.phy astr.gsu.edu Gravitational Lens Since light is bent by a gravity field according to general relativity, there is a possibility of focusing effects like that of a lens when there is a large collection of mass near the path of the light to us. Gravitational lens Wikipedia 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 observer.This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein s general theory of relativity.
