Deutsche Forschungsgemeinschaft (DFG) - Project number 315477589
The goal of this project is to use post-merger gravitational wave signals to constrain dense neutron-star matter and the associated QCD phase transitions. In this project we will further advance numerical tools by developing state-of-the-art GRMHD and hydrodynamics models that accurately capture both the long ringdown behavior in the kilohertz range and potential megahertz signals arising from quark-matter bubble dynamics. The research program includes inferring the neutron-star equation of state from post-merger signals, extending non-perturbative QCD models to encompass both confined and deconfined phases, and formulating a unified chiral effective model to study the impact of chiral phase transitions on neutrino emissions during mergers.
