Pressure and speed of sound in two-flavor color-superconducting quark matter at next-to-leading order
We calculate the next-to-leading order corrections to the pertubative QCD pressure arising from the color superconducting gap at large net baryon density. We find a quite sizeable correction!

Listening to the long ringdown: a novel way to pinpoint the equation of state in neutron-star cores
We show that the behavior of the gravitational wave emission in the post-merger phase of a binary neutron-star merger should show a tight correlation with the pressure and density reached in the cores of maximally massive neutron stars.

Equation of state at neutron-star densities and beyond from perturbative QCD
We show that equations of state that are extremely stiff within the cores of maximally massive neutron stars are incompatible with the behavior of the speed of sound at high densities 25-40$n_\mathrm{sat}$
