  Constraints on primordial lepton asymmetries with full neutrino transport

  Primordial neutrino-antineutrino asymmetries can be constrained through big-bang nucleosynthesis (BBN) relic abundances and cosmic microwave background (CMB) anisotropies, both observables being sensitive to neutrino properties. The latter constraint, which is […]

  Neutrino Trapping and Out-of-Equilibrium Effects in Binary Neutron-Star Merger Remnants

  We study out-of-thermodynamic equilibrium effects in neutron star mergers with 3D general-relativistic neutrino-radiation large-eddy simulations. During merger, the cores of the neutron stars remain cold ($T \sim$ a few MeV) […]

  Neutrino flavor transformation with moments: application to fast flavor instabilities in neutron star mergers

  Neutrino evolution, of great importance in environments such as neutron star mergers (NSMs) because of their impact on explosive nucleosynthesis, is still poorly understood due to the high complexity and […]

  Towards efficient Effective One Body models for generic, non-planar orbits

  Complete waveform models able to account for arbitrary non-planar orbits represent a holy grail in current gravitational-wave astronomy. Here, we take a step towards this direction and present a simple […]
