A Sydney researcher has developed technology to enable astronomers to get sharper pictures of distant galaxies. As a PhD student at Sydney University's School of Physics, Brendon Brewer developed a computer program to help understand gravitational lensing. This is a phenomenon sometimes refe...
Author: Arlie O. Petters My research deals with the mathematical and physical aspects of gravitational lensing, which is the action of gravity on light. In a typical gravitational lensing scenario, light originates from a distant source like a star, galaxy, or quasar, and experiences deflectio...
Astronomers have spotted the most distant Einstein ring ever seen. It gives an insight into both the gravitational lensing galaxy and the more distant magnified galaxy.
Gravitational lensing occurs because massive objects - ranging from stars to entire galaxies - distort the fabric of space-...
