# Constraining neutrino mass with tomographic weak lensing peak counts

@article{Li2019ConstrainingNM, title={Constraining neutrino mass with tomographic weak lensing peak counts}, author={Zack Li and Jia Liu and Jos{\'e} Manuel Zorrilla Matilla and William R. Coulton}, journal={Physical Review D}, year={2019} }

Massive cosmic neutrinos change the structure formation history by suppressing perturbations on small scales. Weak lensing data from galaxy surveys probe the structure evolution and thereby can be used to constrain the total mass of the three active neutrinos. However, much of the information is at small scales where the dynamics are nonlinear. Traditional approaches with second order statistics thus fail to fully extract the information in the lensing field. In this paper, we study constraints…
