Modeling differential rotations of compact stars in equilibriums
Koji Uryu, Antonios Tsokaros, Luca Baiotti +3
Outcomes of numerical relativity simulations of massive core collapses or binary neutron star mergers with moderate masses suggest formations of rapidly and differentially rotating…
Rotational properties of hypermassive neutron stars from binary mergers
Matthias Hanauske, Kentaro Takami, Luke Bovard +4
Determining the differential-rotation law of compact stellar objects produced in binary neutron stars mergers or core-collapse supernovae is an old problem in relativistic astrophy…
On the dynamics of tilted black hole-torus systems
Vassilios Mewes, Filippo Galeazzi, José A. Font +2
We present results from three-dimensional, numerical relativity simulations of a {\it tilted} black hole-thick accretion disc system. The simulations are analysed using tracer part…
Do triaxial supramassive compact stars exist?
Koji Uryu, Antonios Tsokaros, Luca Baiotti +4
We study quasiequilibrium solutions of triaxially deformed rotating compact stars -- a generalization of Jacobi ellipsoids under relativistic gravity and compressible equations of…
Initial-data contribution to the error budget of gravitational waves from neutron-star binaries
Antonios Tsokaros, Bruno C. Mundim, Filippo Galeazzi +2
As numerical calculations of inspiralling neutron-star binaries reach values of accuracy that are comparable with those of binary black holes, a fine budgeting of the various sourc…
Dynamical Mass Ejection from Binary Neutron Star Mergers
David Radice, Filippo Galeazzi, Jonas Lippuner +3
We present fully general-relativistic simulations of binary neutron star mergers with a temperature and composition dependent nuclear equation of state. We study the dynamical mass…
How loud are neutron star mergers?
Sebastiano Bernuzzi, David Radice, Christian D. Ott +3
We present results from the first large parameter study of neutron star mergers using fully general relativistic simulations with finite-temperature microphysical equations of stat…
Numerical relativity simulations of thick accretion disks around tilted Kerr black holes
Vassilios Mewes, José A. Font, Filippo Galeazzi +2
In this work we present 3D numerical relativity simulations of thick accretion disks around tilted Kerr BH. We investigate the evolution of three different initial disk models with…
High-Order Numerical-Relativity Simulations of Binary Neutron Stars
David Radice, Luciano Rezzolla, Filippo Galeazzi
We report simulations of the inspiral and merger of binary neutron stars performed with \texttt{WhiskyTHC}, the first of a new generation of numerical relativity codes employing hi…
Properties of hypermassive neutron stars formed in mergers of spinning binaries
Wolfgang Kastaun, Filippo Galeazzi
We present numerical simulations of binary neutron star mergers, comparing irrotational binaries to binaries of NSs rotating aligned to the orbital angular momentum. For the first…
High-Order Fully General-Relativistic Hydrodynamics: new Approaches and Tests
David Radice, Luciano Rezzolla, Filippo Galeazzi
We present a new approach for achieving high-order convergence in fully general-relativistic hydrodynamic simulations. The approach is implemented in WhiskyTHC, a new code that mak…
Beyond second-order convergence in simulations of binary neutron stars in full general-relativity
David Radice, Luciano Rezzolla, Filippo Galeazzi
Despite the recent rapid progress in numerical relativity, a convergence order less than the second has so far plagued codes solving the Einstein-Euler system of equations. We repo…
Implementation of a simplified approach to radiative transfer in general relativity
Filippo Galeazzi, Wolfgang Kastaun, Luciano Rezzolla +1
We describe in detail the implementation of a simplified approach to radiative transfer in general relativity by means of the well-known neutrino leakage scheme (NLS). In particula…
The Gravitational Universe
The eLISA Consortium, :, P. Amaro Seoane +158
The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and hav…
On the black hole from merging binary neutron stars: how fast can it spin?
Wolfgang Kastaun, Filippo Galeazzi, Daniela Alic +2
The merger of two neutron stars will in general lead to the formation of a torus surrounding a black hole whose rotational energy can be tapped to potentially power a short gamma-r…
The role of the ergosphere in the Blandford-Znajek process
Milton Ruiz, Carlos Palenzuela, Filippo Galeazzi +1
The Blandford-Znajek process, one of the most promising model for powering the relativistic jets from black holes, was initially introduced as a mechanism in which the magnetic fie…
Differentially-rotating neutron star models with a parametrized rotation profile
Filippo Galeazzi, Shin'ichirou Yoshida, Yoshiharu Eriguchi
We analyze the impact of the choice rotation law on equilibrium sequences of relativistic differentially-rotating neutron stars in axisymmetry. The maximum allowed mass for each mo…
