Recent results in and future prospects for weak lensing science

n the past decade, weak gravitational lensing has become one of the best ways of measuring the galaxy-halo connection and cosmological structure growth. Measurements of the dark matter halo masses for galaxies with a given luminosity or stellar mass (observable mass proxies) have revealed a great deal about the connection between halo masses and these more easily observable quantities. I will describe some recent measurements in the Sloan Digital Sky Survey that place constraints on assembly bias, the connection between galaxy or cluster observable properties and the underlying dark matter halo properties beyond halo mass. Next, I will discuss some of the opportunities and challenges for weak lensing science with even larger future surveys, and the prospects for overcoming the challenges to enable weak lensing to achieve its full power as a probe of our cosmological model.

Followed by wine and cheese in Pupin 301.
