The creation of the map was possible thanks to the Optical Gravitational Lensing
Experiment (OGLE) project, one of the largest observing program in the history of the Polish astronomy, launched in 1992.
Using Einstein's prediction, the astronomers used Chandra data and gravitational lensing
to study six quasars, with each comprising of a supermassive blackhole that rapidly consumes matter from the surrounding accretion disk.
Magnified Quasars "Our view of the very distant universe is distorted by gravitational lensing
a lot more than anyone thought, according to two University of Washington astronomers.
Thousands of previously unseen distant galaxies lying behind Abell 370 are also revealed in the image through an effect called gravitational lensing
-- the bending of light due to gravity -- magnifies the background galaxy to make it appear brighter, which allows the astronomers to observe it in more detail than they would otherwise be able to.
It could only be seen because of an effect called "gravitational lensing
" that occurs when massive galaxy clusters bend the light of objects behind them.
He added that other gravitational lensing
alignments should allow more distant stars to be studied.
Kraniotis studied gravitational lensing
of KNdS and KNAdS black hole in , where closed form analytic solutions of the null geodesics and the gravitational lens equations have been obtained versus the Appell-Lauricella generalized hypergeometric functions and the elliptic functions of Weierstrass.
occurs because of galaxies with extreme gravitational power, which magnifies and warps light travelling from the fringes.
Durham's researchers were involved in studying the gravitational lensing
effect that the mass of the Abell 2744 cluster and the filaments exerts on distant galaxies - changing the path of their light, increasing their brightness and twisting their shapes as seen from Earth.
In recent years, the Optical Gravitational Lensing
Experiment, one of several efforts to detect celestial bodies wandering in front of stars in the galaxy, has recorded about 2,000 possible events annually.
