| Abstract: |
Ghostly neutrino particles continue to bring surprises to fundamental physics, from their existence to the phenomenon of neutrino oscillation, which implies their nonzero masses. Their exact masses, among the most curious unknowns beyond the Standard Model of particle physics, can soon be probed by the joint analysis of upcoming cosmological surveys including the Vera Rubin Observatory LSST, Euclid, Simons Observatory, and LiteBIRD. In this talk, I will first discuss ongoing works studying the effects of massive neutrinos. I will then turn the focus to my major efforts of modeling the challenging small-scale, nonlinear regime of cosmic structures where neutrino effects are expected to be strongest. Finally, I will draw a roadmap towards discovering the neutrino mass over the next decade. |
