Signatures of massive neutrinos on Large Scale Structure

Neutrino oscillation experiments have shown that there are at least two massive neutrino eigenstates, in a mass range that can produce observable signatures in current and future cosmological surveys. I will talk about the challenges and progress in correctly including the effects of massive neutrinos in N-body simulations of structure formation. Finally, I will talk about how these simulations can be used to study novel effects in massive neutrino cosmology - in particular, scale-dependent bias of nonlinear objects such as halos and voids on large scales.
