![]() Each image is 3.2 arcseconds on a side, except for 2108+213 which is twice as big. A few more exotic cases are also detected (e.g. The lensing effect is considered strong when the lens galaxy (or cluster of galaxies) is so massive that it produces high order deformations, possibly leading. 0712+472 where two images are blended and the fourth image is not quite visible in this discovery image). Followup observations using radio (MERLIN and VLBA) telescopes and the Hubble Space Telescope in the optical were then used to confirm the systems as gravitational lenses. Background galaxy density 80/ square arcmin Stacked weak-lensing analysis yields a significant detection of the shear (>8 sigma) Analysis exploits the most advanced corrections for ACS-PSF systematics (breathing, CTE) developed for cosmic shear analysis (Rhodes et al. ![]() To find the systems pictured here, 16503 radio sources were examined with the VLA. The action of the galaxy's gravitational field bends the light from the distant object, forming multiple images of it. It works under Windows and Mac OS X in dozens of graphics applications. A gravitational lens is formed when a galaxy lies close to the line of sight to a more distant object - in these cases, a radio-loud quasar. Plugin Galaxy 2 is a plugin for creating special effects and enhancing images with the help of more than 160 basic effects. These radio maps, obtained with the VLA, show 21 gravitational lenses discovered as part of CLASS (Cosmic Lens All-Sky Survey) plus a rediscovery of a previously known lens system.
