Description
I will discuss recent developments in perturbative QCD at high baryon density, focusing on work towards completing the next-to-next-to-next-to-leading order pressure of cold quark matter. This result is expected to substantially improve theoretical control over the high-density regime of the neutron-star-matter equation of state (EoS), with direct implications for model-agnostic EoS inference. In parallel, I will present recent results on the impact of first-order phase transitions on EoS inference, demonstrating that so-called twin-star solutions are currently on the verge of being ruled out.
