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 […]

Numerical relativity simulations of prompt collapse mergers: threshold mass and phenomenological constraints on neutron star properties after GW170817
We determine the threshold mass for prompt (no bounce) black hole formation in equal-mass neutron star (NS) mergers using a new set of 227 numerical relativity simulations. We consider 23 […]
