  Inference of bipolar neutrino flavor oscillations near a core-collapse supernova, based on multiple measurements at Earth

  Neutrinos in compact-object environments, such as core-collapse supernovae, can experience various kinds of collective effects in flavor space, engendered by neutrino-neutrino interactions. These include “bipolar” collective oscillations, which are exhibited […]

  Numerical relativity simulations of the neutron star merger GW190425: microphysics and mass ratio effects

  GW190425 was the second gravitational wave (GW) signal compatible with a binary neutron star (BNS) merger detected by the Advanced LIGO and Advanced Virgo detectors. Despite intense follow-up campaigns, no […]

  Universal Relations for Neutron Star F-Mode and G-Mode Oscillations

  Among the various oscillation modes of neutron stars, f- and g- modes are the most likely to be ultimately observed in binary neutron star mergers. The f-mode is known to […]

  Quasi-normal g-modes of neutron stars with quarks

  Quasi-normal oscillation modes of neutron stars provide a means to probe their interior composition using gravitational wave astronomy. We compute the frequencies and damping times of composition-dependent core g-modes of […]
