As above, so below: assessing extremeness of the neutron-star equation of state based on the unstable branch
Tyler Gorda, Oleg Komoltsev, Aleksi Kurkela +1
Microscopic models of neutron-star matter have been widely used in astrophysical applications. The focus of attention has been on densities up to the maximal densities reached in s…
Constrained Gaussian-process bridge prior for neutron-star equation-of-state inference
Tyler Gorda, Oleg Komoltsev, Aleksi Kurkela +1
We set forth a new method for generating model-agnostic, nonparametric priors for neutron star equation-of-state inference that are stable, causal and thermodynamically consistent…
Perturbative QCD reveals the softening of matter in the cores of massive neutron stars
Oleg Komoltsev
The cores of neutron stars (NSs) contain the densest matter in the universe. Rapid advancements in neutron-star observations allow unprecedented empirical access to cold, ultra-den…
First-order phase transitions in the cores of neutron stars
Oleg Komoltsev
I explore various scenarios for the phase transition within neutron-star matter. I do so by generating large model-agnostic ensemble using Gaussian processes, both with and without…
From existing and new nuclear and astrophysical constraints to stringent limits on the equation of state of neutron-rich dense matter
Hauke Koehn, Henrik Rose, Peter T. H. Pang +10
Through continuous progress in nuclear theory and experiment and an increasing number of neutron-star observations, a multitude of information about the equation of state (EOS) for…
