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…
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…
The role of turbulence and winding in the development of large-scale, strong magnetic fields in long-lived remnants of binary neutron star mergers
Ricard Aguilera-Miret, Carlos Palenzuela, Federico Carrasco +1
We perform a long and accurate Large-Eddy Simulation of a binary neutron star merger, following the newly formed remnant up to 110 milliseconds. The combination of high-order schem…
Universality of the turbulent magnetic field in hypermassive neutron stars produced by binary mergers
Ricard Aguilera-Miret, Daniele Viganò, Carlos Palenzuela
The detection of a binary neutron star merger in 2017 through both gravitational waves and electromagnetic emission opened a new era of multimessenger astronomy. The understanding…
No evidence of kinetic screening in simulations of merging binary neutron stars beyond general relativity
Miguel Bezares, Ricard Aguilera-Miret, Lotte ter Haar +3
We have conducted fully relativistic simulations in a class of scalar-tensor theories with derivative self-interactions and screening of local scales. By using high-resolution shoc…
Turbulent magnetic-field amplification in the first 10 milliseconds after a binary neutron star merger: comparing high-resolution and large eddy simulations
Ricard Aguilera-Miret, Daniele Viganò, Federico Carrasco +2
The detection of binary neutron star mergers represents one of the most important and complex astrophysical discoveries of the recent years. One of the unclear aspects of the probl…
GRMHD large eddy simulations with gradient subgrid-scale model
Daniele Viganò, Ricard Aguilera-Miret, Federico Carrasco +2
The detection of binary neutron star mergers represents one of the most important astrophysical discoveries of the recent years. Due to the extreme matter and gravity conditions an…
