A discontinuous Galerkin method with artificial viscosity geared toward numerical relativity applications
Wolfgang Tichy, Ananya Adhikari, Faezeh Faghihnia Torshizi
Artificial viscosity can be used to deal with shocks and other discontinuities such as star surfaces, that can arise in matter. We explain in detail how a local discontinuous Galer…
Comparing twist-free axisymmetric gravitational waves near the black hole threshold
Ananya Adhikari, Tomáš Ledvinka, Daniela Cors +4
The threshold of black hole formation in axisymmetric vacuum gravity is proving to be more complicated than had been anticipated but, following recent advances, a consensus between…
Numerical Relativity Simulations of Dark Matter Admixed Binary Neutron Stars
Edoardo Giangrandi, Hannes R. Rüter, Nina Kunert +7
Binary neutron star mergers provide insight into strong-field gravity and the properties of ultra-dense nuclear matter. These events offer the potential to search for signatures of…
Neutron star evolution by combining discontinuous Galerkin and finite volume methods
Ananya Adhikari, Wolfgang Tichy, Liwei Ji +1
We present here a new hybrid scheme that combines a discontinuous Galerkin (DG) method with compact finite volume (FV) and finite difference (FD) methods. The computational mesh is…
The new discontinuous Galerkin methods based numerical relativity program Nmesh
Wolfgang Tichy, Liwei Ji, Ananya Adhikari +2
Interpreting gravitational wave observations and understanding the physics of astrophysical compact objects such as black holes or neutron stars requires accurate theoretical model…
Second release of the CoRe database of binary neutron star merger waveforms
Alejandra Gonzalez, Francesco Zappa, Matteo Breschi +15
We present the second data release of gravitational waveforms from binary neutron star merger simulations performed by the Computational Relativity (CoRe) collaboration. The curren…
Investigating GW190425 with numerical-relativity simulations
Reetika Dudi, Ananya Adhikari, Bernd Brügmann +7
The third observing run of the LIGO-Virgo collaboration has resulted in about hundred gravitational-wave triggers including the binary neutron star merger GW190425. However, none o…
CoRe database of binary neutron star merger waveforms and its application in waveform development
Tim Dietrich, David Radice, Sebastiano Bernuzzi +7
We present the Computational Relativity CoRe collaboration's public database of gravitational waveforms from binary neutron star mergers. The database currently contains 367 wavefo…
Fluctuation-dissipation in accelerated frames
Ananya Adhikari, Krishnakanta Bhattacharya, Chandramouli Chowdhury +1
An uniformly accelerated (Rindler) observer will detect particles in the Minkowski vacuum, known as Unruh effect. The spectrum is thermal and the temperature is given by that of th…
