Analysis of systematic bias on lensing analysis using optical clusters

Presenter: Tomomi Sunayama (Kavli IPMU)

One of the most important systematics for optically selected clusters is the projection effect. In this talk, I present how the projection effect can bias the measurement of the cosmological parameters and how the projection effect can be modeled to achieve more accurate measurements.
