Astro Seminar: "Weak Lensing in the Nonlinear Regime"
Jia Liu (Princeton)
Within the next decade, galaxy and CMB lensing datasets of unprecedented precision will come online from large surveys (DES, HSC, LSST, Euclid, WFIRST, AdvACT, SPT-3G, CMB-S4, etc.). These surveys will be sensitive to structure evolution in the strongly nonlinear regime, warranting the study of higher-order (non-Gaussian) statistics that contain information beyond the traditional second-order statistics. In this talk, I will present our recent study of one simple non-Gaussian statistic, the lensing peaks - their origin (1606.01318), application to galaxy lensing data (1412.0757), and forecasts for CMB lensing (1608.03169).
