GRACE: An Open-Source Framework for GPU-Accelerated Numerical Relativity
Carlo Musolino, Christian Ecker, Konrad Topolski +6
We present GRACE, a new GPU-accelerated numerical-relativity framework designed to run efficiently on heterogeneous high-performance computing platforms. Developed from scratch and…
Towards holographic color superconductivity in QCD
Jesús Cruz Rojas, Tuna Demircik, Christian Ecker +1
We extend the holographic V-QCD model by introducing a charged scalar field sector to represent the condensation of paired quark matter in the deconfined phase. By incorporating th…
General gravitational properties of neutron stars: curvature invariants, binding energy, and trace anomaly
Iván Garibay, Christian Ecker, Luciano Rezzolla
We investigate the behavior of curvature invariants for a large ensemble of neutron stars built with equations of state (EOSs) that satisfy constraints from nuclear theory and pert…
On the maximum compactness of neutron stars
Luciano Rezzolla, Christian Ecker
The stellar compactness, that is, the dimensionless ratio between the mass and radius of a compact star, , plays a fundamental role in characterising the gravit…
Strong model-agnostic constraints for twin-star solutions
Sofia Blomqvist, Christian Ecker, Tyler Gorda +1
We perform a model-agnostic Bayesian analysis of the neutron-star-matter equation of state (EoS), using known ab-initio constraints and astrophysical observations to limit its beha…
Listening to the long ringdown: A novel way to pinpoint the EOS in neutron-star cores
Christian Ecker, Tyler Gorda, Aleksi Kurkela +1
Gravitational waves (GWs) from binary neutron star (BNS) merger remnants complement constraints from the inspiral phase, mass-radius measurements, and microscopic theory by providi…
