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…
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…
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…
Locating the QCD critical point with neutron-star observations
Christian Ecker, Niko Jokela, Matti Järvinen
We present a probabilistic model for the QCD critical endpoint (CEP) and the equation of state (EOS) at -equilibrium, constrained by neutron-star observations. Using a hybrid fr…
Physics-Informed Priors Improve Gravitational-Wave Constraints on Neutron-Star Matter
Spencer J. Magnall, Christian Ecker, Luciano Rezzolla +2
Gravitational-wave astronomy shows great promise in determining nuclear physics in a regime not accessible to terrestrial experiments. We introduce physics-informed priors constrai…
