Core-Collapse Supernovae, Neutrinos, and Gravitational Waves
C. D. Ott, E. P. O'Connor, S. Gossan +3
Core-collapse supernovae are among the most energetic cosmic cataclysms. They are prodigious emitters of neutrinos and quite likely strong galactic sources of gravitational waves.…
Three-Dimensional General-Relativistic Hydrodynamic Simulations of Binary Neutron Star Coalescence and Stellar Collapse with Multipatch Grids
C. Reisswig, R. Haas, C. D. Ott +4
We present a new three-dimensional general-relativistic hydrodynamic evolution scheme coupled to dynamical spacetime evolutions which is capable of efficiently simulating stellar c…
General-Relativistic Simulations of Three-Dimensional Core-Collapse Supernovae
C. D. Ott, E. Abdikamalov, P. Moesta +6
We study the three-dimensional (3D) hydrodynamics of the post-core-bounce phase of the collapse of a 27-solar-mass star and pay special attention to the development of the standing…
The runaway instability in general relativistic accretion disks
O. Korobkin, E. Abdikamalov, N. Stergioulas +4
When an accretion disk falls prey to the runaway instability, a large portion of its mass is devoured by the black hole within a few dynamical times. Despite decades of effort, it…
A New Spherical Harmonics Scheme for Multi-Dimensional Radiation Transport I: Static Matter Configurations
David Radice, Ernazar Abdikamalov, Luciano Rezzolla +1
Recent work by McClarren & Hauck [29] suggests that the filtered spherical harmonics method represents an efficient, robust, and accurate method for radiation transport, at least i…
Correlated Gravitational Wave and Neutrino Signals from General-Relativistic Rapidly Rotating Iron Core Collapse
C. D. Ott, E. Abdikamalov, E. O'Connor +6
We present results from a new set of 3D general-relativistic hydrodynamic simulations of rotating iron core collapse. We assume octant symmetry and focus on axisymmetric collapse,…
