Subject: Constraints on σ8 from joint analysis of lensing and stacking galaxy clusters

In this talk I will speak about recent results of constraining the cosmological parameter, σ8, from a joint analysis of gravitational lensing and stacking clusters of galaxies. Two methods were used to get σ8, one assuming a prior on galaxy bias, and the other making no such assumption. Both methods agreed with one another and previous results for σ8 from Planck, WMAP, and just lensing.
