Multi-messenger and multi-band signal from first-order phase transitions in proto-neutron stars
Christian Ecker, Mauro Giliberti, Luciano Rezzolla
A first-order phase transition (PT) alters a compact star on two scales: globally, via growth of a quark-matter core, and microscopically, via collision of quark bubbles, driving a…
Black hole-neutron star binaries with high spins and large mass asymmetries: III. Properties of the ejected material and its electromagnetic signatures
Konrad Topolski, Samuel D. Tootle, Paramvir Singh +2
Compact binary systems consisting of a black hole (BH) and a neutron star (NS) are expected to provide detectable signals both in the gravitational wave and in the electromagnetic…
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…
Dynamical response of twin stars to perturbations
Shamim Haque, Luciano Rezzolla, Ritam Mallick
If a strong first-order phase transition takes place at sufficiently high rest-mass densities in the equation of state (EOS) modelling compact stars, a new branch will appear in 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…
Formation of gravastars
Daniel Jampolski, Luciano Rezzolla
Regular black holes and horizonless black hole mimickers offer mathematically consistent alternatives to address the challenges posed by standard black holes. However, the formatio…
Towards a Non-singular Paradigm of Black Hole Physics
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18
The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…
Black hole - neutron star binaries with high spins and large mass asymmetries: II. Properties of dynamical simulations
Konrad Topolski, Samuel Tootle, Luciano Rezzolla
Black hole (BH) - neutron star (NS) binary mergers are not only strong sources of gravitational waves (GWs), but they are also candidates for joint detections in the GW and electro…
Black hole-neutron star binaries with high spins and large mass asymmetries: I. Properties of quasi-equilibrium sequences
Konrad Topolski, Samuel Tootle, Luciano Rezzolla
Black hole - neutron star (BHNS) mergers are a promising target of current gravitational-wave (GW) and electromagnetic (EM) searches, being the putative origin of ultra-relativisti…
Can light-rings self-gravitate?
Francesco Di Filippo, Luciano Rezzolla
In a spherically symmetric and static spacetime of a compact object, such as that of a Schwarzschild black hole, the light-ring is a 2-sphere where photons experience the only poss…
Phenomenological template family for black-hole coalescence waveforms
P. Ajith, S. Babak, Y. Chen +15
Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a…
