Constraining the Neutrino Mass with the Drifting Coefficient of the Field Cluster Mass Function

25 Mar 2020 Ryu Suho Seoul National University Lee Jounghun Seoul National University

A new diagnostics to break the degeneracy between the total neutrino mass ($M_{\nu}$) and the primordial power spectrum amplitude ($\sigma_{8}$) by using the drifting coefficient of the field cluster mass function is presented. Analyzing the data from the Cosmological Massive Neutrino Simulations, we first determine the numerical mass functions of the field clusters at various redshifts... (read more)
