2D End-to-End Modeling of Kilonovae from Binary Neutron Star Merger Remnants

Lieke Sippens Groenewegen, Sanjana Curtis, Philipp Mösta +2

We investigate the kilonova emission resulting from outflows produced in a three-dimensional (3D) general-relativistic magnetohydrodynamic (GRMHD) simulation of a hypermassive neut…

A resistive MHD module in the GPU-accelerated GRMHD code GRaM-X

Sara Azizi, Swapnil Shankar, Philipp Mösta +2

Relativistic macroscopic plasma dynamics can be described by general-relativistic magnetohydrodynamics. In many high-energy astrophysical settings, such as the interior dynamics of…

Gravitational waves from magnetorotational core-collapse supernovae using 3D GRMHD simulations: effect of rotation and magnetic fields

Sophia C. Schnauck, Swapnil Shankar, Philipp Mösta +2

We investigate the gravitational wave emission for 10 supernova progenitors from magnetorotational core-collapse to the supernova explosion using fully three-dimensional dynamical-…

A Black Hole is Born: 3D GRMHD Simulation of Black Hole Formation from Core-Collapse

Goni Halevi, Swapnil Shankar, Philipp Mösta +2

We present the first three-dimensional, fully general-relativistic magnetohydrodynamic (3D GRMHD) simulation of a black hole (BH) formed from the collapsed core of a massive star.…

3D full-GR simulations of magnetorotational core-collapse supernovae on GPUs: A systematic study of rotation rates and magnetic fields

Swapnil Shankar, Philipp Mösta, Roland Haas +1

We present a series of fully three-dimensional, dynamical-spacetime general relativistic magnetohydrodynamics (GRMHD) simulations of core-collapse supernovae (CCSNe) for a progenit…
