Neutron star-black hole mergers with a nuclear equation of state and neutrino cooling: Dependence in the binary parameters

- F. Foucart, M. Deaton,
+7 authors B. Szilágyi - Physics
- 6 May 2014

We present a first exploration of the results of neutron star-black hole mergers using black hole masses in the most likely range of 7M_⊙ –10M_⊙, a neutrino leakage scheme, and a modeling of the… Expand

Effects of the microphysical Equation of State in the mergers of magnetized Neutron Stars With Neutrino Cooling

- C. Palenzuela, S. Liebling,
+4 authors M. Anderson - Physics
- 7 May 2015

We study the merger of binary neutron stars using different realistic, microphysical nuclear equations of state, as well as incorporating magnetic field and neutrino cooling effects. In particular,… Expand

BLACK HOLE FORMATION IN FAILING CORE-COLLAPSE SUPERNOVAE

- E. O’Connor, C. Ott
- Physics
- 27 October 2010

We present results of a systematic study of failing core-collapse supernovae and the formation of stellar-mass black holes (BHs). Using our open-source general-relativistic 1.5D code GR1D equipped… Expand

Unequal mass binary neutron star mergers and multimessenger signals

- L. Lehner, S. Liebling,
+4 authors D. Neilsen - Physics
- 1 March 2016

We study the merger of binary neutron stars with different mass ratios adopting three different realistic, microphysical nuclear equations of state, as well as incorporating neutrino cooling effects.… Expand

Post-merger evolution of a neutron star-black hole binary with neutrino transport

- F. Foucart, E. O’Connor,
+7 authors B. Szilágyi - Physics
- 13 February 2015

We present a first simulation of the post-merger evolution of a black hole-neutron star binary in full general relativity using an energy-integrated general-relativistic truncated moment formalism… Expand

A new open-source code for spherically symmetric stellar collapse to neutron stars and black holes

- E. O’Connor, C. Ott
- Physics
- 14 December 2009

We present the new open-source spherically symmetric general-relativistic (GR) hydrodynamics code GR1D. It is based on the Eulerian formulation of GR hydrodynamics (GRHD) put forth by… Expand

AN OPEN-SOURCE NEUTRINO RADIATION HYDRODYNAMICS CODE FOR CORE-COLLAPSE SUPERNOVAE

- E. O’Connor
- Physics
- 25 November 2014

We present an open-source update to the spherically-symmetric, general-relativistic hydrodynamics, core-collapse supernova (CCSN) code GR1D (O'Connor & Ott, 2010, CQG, 27, 114103). The source code is… Expand

A NEW MONTE CARLO METHOD FOR TIME-DEPENDENT NEUTRINO RADIATION TRANSPORT

- E. Abdikamalov, A. Burrows,
+7 authors P. Institute - Physics
- 13 March 2012

Monte Carlo approaches to radiation transport have several attractive properties such as simplicity of implementation, high accuracy, and good parallel scaling. Moreover, Monte Carlo methods can… Expand

Neutrino-nucleon scattering in supernova matter from the virial expansion

- C. Horowitz, O. L. Caballero, Zidu Lin, E. O’Connor, A. Schwenk
- Physics
- 16 November 2016

We generalize our virial approach to study the neutral current neutrino response of nuclear matter at low densities. In the long-wavelength limit, the virial expansion makes model-independent… Expand

General Relativistic Three-Dimensional Multi-Group Neutrino Radiation-Hydrodynamics Simulations of Core-Collapse Supernovae

- L. Roberts, C. Ott, R. Haas, E. O’Connor, P. Diener, E. Schnetter
- Physics
- 26 April 2016

We report on a set of long-term general-relativistic three-dimensional (3D) multi-group (energy-dependent) neutrino-radiation hydrodynamics simulations of core-collapse supernovae. We employ a full… Expand
