# Do dark matter halos explain lensing peaks

@article{Matilla2016DoDM, title={Do dark matter halos explain lensing peaks}, author={Jos{\'e} Manuel Zorrilla Matilla and Zolt{\'a}n Haiman and Daniel J. Hsu and Arushi Gupta and Andrea Petri}, journal={Physical Review D}, year={2016}, volume={94}, pages={083506} }

We have investigated a recently proposed halo-based model, Camelus, for predicting weak-lensing peak counts, and compared its results over a collection of 162 cosmologies with those from N-body simulations. While counts from both models agree for peaks with $\mathcal{S/N}>1$ (where $\mathcal{S/N}$ is the ratio of the peak height to the r.m.s. shape noise), we find $\approx 50\%$ fewer counts for peaks near $\mathcal{S/N}=0$ and significantly higher counts in the negative $\mathcal{S/N}$ tail…
