Cosmology based on $f(R)$ gravity with $\mathcal{O}(1)$ eV sterile neutrino

A. S. Chudaykin, D. S. Gorbunov, A. A. Starobinsky +1

We address the cosmological role of an additional $\mathcal{O}(1)$ eV sterile neutrino in modified gravity models. We confront the present cosmological data with predictions of the FL…
