The imprint of individual neutron star spins on ejecta, -process nucleosynthesis, and kilonovae in binary neutron star mergers
Beyhan Karakas, Rahime Matur, David Radice +2
To leading order, the gravitational-wave (GW) signal from binary neutron stars depends on the individual spins, and , only through the effective spin parameter $χ_{\rm e…
Wave Optics Effects from Gravitational Wave Propagation Through Dark Matter Halos
Annamalai P. Shanmugaraj, Roland Haas, Erik Schnetter +1
Gravitational wave (GW) propagation is usually studied under the geometric optics approximation. But when GWs propagate through structures of sizes similar to their wavelength, thi…
A Reproducible Black Hole-Neutron Star Merger Gallery Example for the Einstein Toolkit
Rahime Matur, Beyhan KarakaÅ, Roland Haas +3
Black hole-neutron star mergers, together with binary neutron star mergers, are key laboratories for neutron star physics. They enable us to probe merger dynamics imprinted in grav…
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.…
