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…
Stability of hypermassive neutron stars with realistic rotation and entropy profiles
Nishad Muhammed, Matthew D. Duez, Pavan Chawhan +7
Binary neutron star mergers produce massive, hot, rapidly differentially rotating neutron star remnants; electromagnetic and gravitational wave signals associated with the subseque…
High angular momentum hot differentially rotating equilibrium star evolutions in conformally flat spacetime
Patrick Chi-Kit Cheong, Nishad Muhammed, Pavan Chawhan +5
The conformal flatness approximation to the Einstein equations has been successfully used in many astrophysical applications such as initial data constructions and dynamical simula…
Quantum Mechanics in Wavelet Basis
Pavan Chawhan, Raghunath Ratabole
We describe a multi-scale resolution approach to analyzing problems in Quantum Mechanics using Daubechies wavelet basis. The expansion of the wavefunction of the quantum system in…
