Problem 3: Gravitational Lensing by a Galaxy
The Einstein Cross is a set of five images of a quasar at redshift z=1.695,
shining through a spiral galaxy, 2237+0305, at z=0.039. Four of the images
lie close to a circle of radius 0.9 arcseconds.
(a) What is the distance to the spiral galaxy?
(b) Estimate the mass of the spiral galaxy within this radius. [Hint:
