From mergers to collapse: scalarisation dynamics in neutron star binaries
Llibert Aresté Saló, Ricard Aguilera-Miret, Miguel Bezares +1
We present the first fully non-linear evolutions of binary neutron star mergers in a moving-punctures approach in Einstein-scalar-Gauss-Bonnet gravity. We study both linear and qua…
Impact of magnetic field gradients on the development of the MRI: Applications to binary neutron star mergers and proto-planetary disks
T. Celora, C. Palenzuela, D. Viganò +1
The magneto-rotational instability (MRI) is widely believed to play a central role in generating large-scale, poloidal magnetic fields during binary neutron star mergers. However,…
MHDuet : a high-order General Relativistic Radiation MHD code for CPU and GPU architectures
Carlos Palenzuela, Miguel Bezares, Steven Liebling +12
We present MHDuet, an open source evolution code for general relativistic magnetohydrodynamics with neutrino transport. The code solves the full set of Einstein equations coupled t…
Robustness of Magnetic Field Amplification in Neutron Star Mergers
Ricard Aguilera-Miret, Jan-Erik Christian, Stephan Rosswog +1
The dynamics of a binary neutron stars merger is governed by physics under the most extreme conditions, including strong spacetime curvature, ultra-high matter densities, luminous…
Delayed jet launching in binary neutron star mergers with realistic initial magnetic fields
Ricard Aguilera-Miret, Carlos Palenzuela, Federico Carrasco +2
We analyze a long-lived hyper-massive neutron star merger remnant (post-merger lifetime ms) that has been obtained via large eddy simulations with a gradient subgrid-scale m…
