Query: Hiding neutrino mass in modified gravity cosmologies   Cosmological observables show a dependence with the neutrino mass, which is
partially degenerate with parameters of extended models of gravity. We study
and explore this degeneracy in Horndeski generalized scalar-tensor theories of
gravity. Using forecasted cosmic microwave background and galaxy power spectrum
datasets, we find that a single parameter in the linear regime of the effective
theory dominates the correlation with the total neutrino mass. For any given
mass, a particular value of this parameter approximately cancels the power
suppression due to the neutrino mass at a given redshift. The extent of the
cancellation of this degeneracy depends on the cosmological large-scale
structure data used at different redshifts. We constrain the parameters and
functions of the effective gravity theory and determine the influence of
gravity on the determination of the neutrino mass from present and future
surveys.
