Description
Neutron star mergers provide a unique laboratory for the study of strong-field gravity coupled to QCD in extreme conditions. Simulations to date show that potential first-order phase transitions in the phase diagram of quantum chromodynamics may be accessed during the merger. In this talk I will argue that a phase transition would result in the emission of high frequency gravitational waves from bubble collisions, and I will provide with a rough estimate of the peak frequency and strain amplitude. Additionally, I will report on ongoing work in the study of bubble dynamics in QCD-like phase transitions, required for a better characterization of the emission from first-order phase transition during neutron star mergers.
