Cosmology with weak gravitational lensing: challenges and opportunities
Weak gravitational lensing surveys are driving a new era of precision cosmology. Obtaining unbiased cosmological constraints from such data sets requires accurate modeling of the imprint of galaxy formation on the large-scale distribution of matter, and of intrinsic alignment correlations between galaxy shapes. In this talk, I will describe current efforts to advance our understanding of these phenomena. In addition, the deluge of data from next generation surveys will allow us to exploit new applications for cosmology. I will present a new method to constrain inflationary models of the early Universe from the measurement of galaxy shapes.
