Abstract: Over the next decade, neutrino astronomy will probe the rich astrophysics of neutrino production in the sky, including neutrinos from the Sun, core-collapse supernova (e.g., SN 1987A), and relativistic jets (e.g., blazar TXS 0506+056). On the observational side of this new era, the Super-Kamiokande with Gadolinium, Jiangmen Underground Neutrino Observatory, XENON, and future liquid scintillator neutrino experiments usher in a new generation of multi-purpose neutrino detectors designed to open new avenues for potentially observing currently undetected neutrinos.

Abstract: I study the flavor evolution of a dense neutrino gas by considering vacuum contributions, mat-ter effects and neutrino self-interactions. Assuming a system of two flavors in a uniform matter background, the time evolution of the many-body system in discretized momentum space is com-puted. The multi-angle neutrino-neutrino interactions are treated exactly and compared to both the single-angle approximation and mean field calculations.  I study various configurations of up to twenty neutrinos.
