The Cosmic Quest for Neutrino Mass

Explore the mysteries of neutrinos in this Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium talk. Delve into the cosmic quest for neutrino mass with speaker Marilena LoVerde from the University of Washington. Learn about the importance of neutrinos in the early Universe and their current contribution to the energy budget. Discover the major experimental goals of the current decade aimed at measuring neutrino mass scale and ordering. Examine the physical effects of neutrino mass, including the roles of geometry and structure on constraints. Investigate the peculiar preference for "negative neutrino mass" in some dataset combinations and hints of detection in others. Gain insights into novel astrophysical probes of neutrino mass that may help resolve current conundrums and contribute to validating relic neutrino detection in the late Universe.
