Abstract: | Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe.
In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion
rate of the universe, and distinguish between modified gravity and dark energy explanations for the acceleration of the universe.
We also discuss requirements on the control of systematic errors so that the systematics do not appreciably degrade the power
of weak lensing as a cosmological probe. |
