Title: Strong lensing events in the CFIS survey and weak lensing cluster masses from archival CFHT imaging data

Presenter: Raphael Gavazzi


I will present ongoing work on the CFIS imaging data in which we automatically search galaxy-scale strong lensing events as a probe of the small scale mass content of galaxies. On larger cluster of galaxies mass scales, I will present results on the systematic analysis of archival CFHT/Megacam (and Subaru/Suprimecam) images. Weak lensing masses for ~120 clusters are obtained hence allowing very accurate calibration of cluster mass proxies, like SZ or X-rays.
