  Dark Population Transfer Mechanism for Sterile Neutrino Dark Matter

  We present a mechanism for producing a cosmologically significant relic density of one or more sterile neutrinos. This scheme invokes two steps: First, a population of “heavy” sterile neutrinos is […]

  Exploring entanglement and spectral split correlations in three-flavor collective neutrino oscillations

  In environments with prodigious numbers of neutrinos, such as core-collapse supernovae, neutron star mergers, or the early universe, neutrino-neutrino interactions are dynamically significant. They can dominate neutrino flavor evolution and […]

  Beyond Hawking evaporation of black holes formed by dark matter in compact stars

  The memory burden effect is an explicit resolution to the information paradox by which an evaporating black hole acquires quantum hair, which then suppresses its rate of mass loss with […]

  Influence of neutrino-electron scattering and neutrino-pair annihilation on hypermassive neutron star

  We investigate the influence of inelastic neutrino microphysics in general-relativistic magnetohydrodynamics simulations of a hypermassive neutron star. In particular, we include species/energy groups coupled neutrino-matter interactions, such as inelastic neutrino-electron […]

  Nuclear excited states may be key to search for new flavor-violating physics

  Collider-based experiments continue to push the energy frontier in search of new particles.
