Gravitational Lensing
Weak Gravitational Lensing in the Hubble Deep Field
The image shows galaxies in the Hubble Deep Field, a very deep exposure of distant galaxies obtained by the Hubble Space Telescope. The overlay in the lower left hand corner represents the distortion of background images due to gravitational lensing expected from the dark matter "haloes" of the foreground galaxies, indicated by red ellipses. The blue polarization "sticks" indicate the distortion.
I am currently working on the Canada-France-Hawaii Legacy Survey
