We present an axisymmetric failed supernova simulation beyond black hole formation, for the first time with numerical relativity and two-moment multi energy neutrino transport. To ensure stable numerical evolution, we use an excision method for neutrino radiation-hydrodynamics within the inner part of black hole domain. We demonstrate that our excision method is capable to stably evolve the radiation-hydrodynamics in dynamical black hole spacetime. As a remarkable signature of the final moment of PNS, we find the emergence of high energy neutrinos. Those high energy neutrinos are associated with the proto-neutron star shock surface being swallowed by the central black hole and could be a possible observable of failed supernovae.

  1. Strongly interacting matter with criticality induced by modified excluded volume in core-collapse supernova simulations

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    Modified-excluded-volume EOS with continuous van der Waals phase transition yields CCSN explosions and a several-millisecond neutrino burst, while the same EOS under Gibbs construction fails to explode.

  2. Neutrino pair annihilation driven jets from black-hole torus systems

    astro-ph.HE 2025-06 conditional novelty 5.0 of 10

    Neutrino pair annihilation in black hole-torus systems launches relativistic fireballs with isotropic energies up to about 10^51 erg and durations around 0.1 s, which can account for faint short GRBs and GRB precursors.

  3. Parameter Estimation Horizon of Core-Collapse Supernovae with a Network of Gravitational-Wave Detectors

    astro-ph.HE 2026-08 conditional novelty 4.0 of 10

    A CNN can recover supernova peak frequency out to about 30 kpc and rotation/amplitude out to 200-250 kpc with current networks, extending to roughly 300 kpc and 2-2.5 Mpc with third-generation detectors.
