  Determining the phase structure of Quantum Chromodynamics (QCD) and its
Equation of State (EOS) at densities and temperatures realized inside neutron
stars and their mergers is a long-standing open problem. The holographic V-QCD
framework provides a model for the EOS of dense and hot QCD, which describes
the deconfinement phase transition between a dense baryonic and a quark matter
phase. We use this model in fully general relativistic hydrodynamic (GRHD)
simulations to study the formation of quark matter and the emitted
gravitational wave signal of binary systems that are similar to the first ever
observed neutron star merger event GW170817.
