  Towards Probing the Diffuse Supernova Neutrino Background in All Flavors

  Fully understanding the average core-collapse supernova requires detecting the diffuse supernova neutrino background (DSNB) in all flavors. While the DSNB $\bar{\nu}_e$ flux is near detection, and the DSNB $\nu_e$ flux […]

  Neutrino Fast Flavor Instability in Three Dimensions

  Core-collapse supernovae and neutron star mergers are profligate producers of neutrinos that would be observable at neutrino observatories on Earth if they occur sufficiently close.

  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 […]
