Neutrino Fast Flavor Instability in Three Dimensions
Neutrino flavor instabilities have the potential to shuffle neutrinos between electron, mu, and tau flavor states, modifying the core-collapse supernova mechanism and the heavy elements ejected from neutron star mergers. […]

Statistical significance of the sterile-neutrino hypothesis in the context of reactor and gallium data
We evaluate the statistical significance of the 3+1 sterile-neutrino hypothesis using $\nu_e$ and $\bar\nu_e$ disappearance data from reactor, solar and gallium radioactive source experiments. Concerning the latter, we investigate the […]

Probing Neutron Stars’ Composition with g-mode Oscillations
What can we learn from observing the “ringing” (oscillation modes) of astrophysical objects? Similar to how seismologists study the density profile and chemical constituents of the Earth using earthquakes, stellar oscillation […]

Radiation hydrodynamics modeling of kilonovae with SNEC
We develop a method to compute synthetic kilonova light curves that combines numerical relativity simulations of neutron star mergers and the SNEC radiation-hydrodynamics code. We describe our implementation of initial […]
