Cosmology Seminar Announcement Chris Vale UC Berkeley " Weak Lensing and Dark Energy " Date: Thursday, April 14, 2005 416 Phy/Geo Time: 12:10 pm. Abstract: Since the first detection five years ago, weak gravitational lensing by large scale structure has emerged as an increasingly powerful probe of cosmology. I examine the current state of the art from a theorists point of view using numerical simulations, and speculate on the improvements that will be required if we are to constrain dark energy using future weak lensing surveys.
