标题： Failed supernova simulations beyond black hole formation

摘要： 我们首次通过数值相对论和两矩量多能量中微子输运进行了超越黑洞形成的轴对称失败超新星模拟。 为了确保数值演化的稳定性，我们在黑洞区域的内部使用了中微子辐射-流体力学的切除方法。 我们证明了我们的切除方法能够在动态黑洞时空中稳定地演化辐射-流体力学。 作为原中子星最终时刻的显著特征，我们发现了高能中微子的出现。 这些高能中微子与中心黑洞吞噬原中子星激波表面有关，可能是失败超新星的一个可能可观测信号。 显示英文摘要

摘要： 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.
