Axisymmetric hydrodynamics in numerical relativity: treating coordinate singularity, artificial heating and modeling MHD instabilities
Pavan Chawhan, Matthew D. Duez, Francois Foucart +2
Two-dimensional axisymmetric simulations of binary neutron star (BNS) merger remnant are a cheap alternative to 3D simulations. To maintain realism for secular timescales, simulati…

Influence of neutrino-electron scattering and neutrino-pair annihilation on hypermassive neutron star
Patrick Chi-Kit Cheong, Francois Foucart, Harry Ho-Yin Ng +4
We investigate the influence of inelastic neutrino microphysics in general-relativistic magnetohydrodynamics simulations of a hypermassive neutron star. In particular, we include s…

Energy-dependent and energy-integrated two-moment general-relativistic neutrino transport simulations of hypermassive neutron star
Patrick Chi-Kit Cheong, Francois Foucart, Matthew D. Duez +3
We compare two-moment based \emph{energy-dependent} and 3 variants of \emph{energy-integrated} neutrino transport general-relativistic magnetohydrodynamics simulations of hypermass…
