Higher-derivative gravitational effective field theories are generically weakly hyperbolic
Farid Thaalba, Fernando Abalos, Miguel Bezares
The paper studies the initial‑value problem for metric higher‑derivative gravitational effective field theories and demonstrates that any such theory with characteristic speeds ind…
Scalar emission from binary neutron stars in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Thiago Assumpcao +2
We investigate the scalar emission from binary neutron stars in shift-symmetric scalar-tensor theories with kinetic screening (-essence), using 3+1 numerical simulations in the…
Neutron star evolution with the Bemfica-Disconzi-Noronha-Kovtun viscous hydrodynamics framework
Harry L. H. Shum, Fernando Abalos, Yago Bea +3
The recently proposed first-order viscous relativistic hydrodynamics formulation by Bemfica, Disconzi, Noronha, and Kovtun (commonly known as the BDNK formulation) has been shown t…
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…
A well-posed BSSN-type formulation for scalar-tensor theories of gravity with second-order field equations
Harry L. H. Shum, Llibert Aresté Saló, Farid Thaalba +2
Recent developments in the modified harmonic and modified puncture gauges have opened new possibilities for performing stable numerical evolutions beyond General Relativity. In thi…
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…
