Abstract

In this Letter, we report the observational constraints on the Hu-Sawicki ƒ (R) theory derived from weak lensing peak abundances, which are closely related to the mass function of massive halos. In comparison with studies using optical or x-ray clusters of galaxies, weak lensing peak analyses have the advantages of not relying on mass-baryonic observable calibrations. With observations from the Canada-France-Hawaii-Telescope Lensing Survey, our peak analyses give rise to a tight constraint on the model parameter |ƒ_R₀| for n=1. The 95% C.L. is log₁₀|ƒ_R0|<−4.82 given WMAP9 priors on (Ω_m, A_s). With Planck15 priors, the corresponding result is log₁₀|ƒ_R₀|<−5.16.
