Deflection angle Introduction to <strong>Gravitational</strong> <strong>Lensing</strong> Applications Brightness g magnification g • Light flux F is the product of surface brightness g I and solid angle dw. Since I is contant, F is proportional to dw • dw = A/D 2 • A S/D S 2 < AL/D L 2 => Fs
How cosmologists g and astrophysicists make use of these effects?
