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…

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 f…

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…

Constraining the equation of state in neutron-star cores via the long-ringdown signal

Christian Ecker, Tyler Gorda, Aleksi Kurkela +1

Multimessenger signals from binary neutron star (BNS) mergers are promising tools to infer the largely unknown properties of nuclear matter at densities that are presently inaccess…

Prompt Black Hole Formation in Binary Neutron Star Mergers

Christian Ecker, Konrad Topolski, Matti Järvinen +1

We carry out an in-depth analysis of the prompt-collapse behaviour of binary neutron star (BNS) mergers. To this end, we perform more than general relativistic BNS merger simu…
