This region i s relevant for core-collapse supernovae and binary neutron star mergers. I present a new framework for the QCD equation of state which combines the holographic V-QCD model with traditional nuclear theory models\, and cover s all relevant temperatures and densities. I use V-QCD to describe both nu clear and quark matter at high densities\, with temperature dependence est imated by employing a simple van der Waals hadron gas model. At low densit ies\, I use DD2 Hempel-Schaffner-Bielich model\, i.e.\, a statistical mode l for nuclear matter with relativistic mean field interactions. The result ing "hybrid" model gives predictions\, among other things\, for the mixed quark-hadron phase and the location of the critical endpoint of the quark- hadron transition. I will also discuss preliminary results from neutron st ar merger simulations which use this model.\n LOCATION:https://researchseminars.org/talk/ATP2022/8/ END:VEVENT END:VCALENDAR
