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…
Equation of state at neutron-star densities and beyond from perturbative QCD
Oleg Komoltsev, Rahul Somasundaram, Tyler Gorda +3
We explore the consequences of imposing robust thermodynamic constraints arising from perturbative Quantum Chromodynamics (QCD) when inferring the dense-matter equation-of-state (E…
Strongly interacting matter exhibits deconfined behavior in massive neutron stars
Eemeli Annala, Tyler Gorda, Joonas Hirvonen +4
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear matter melts into deconfined…
Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state
Tyler Gorda, Oleg Komoltsev, Aleksi Kurkela +1
The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities.…
QCD in the cores of neutron stars
Oleg Komoltsev
I discuss why state-of-the art perturbative QCD calculations of the equation of state at large chemical potential that are reliable at asymptotically high densities constrain the s…
Ab-initio QCD calculations impact the inference of the neutron-star-matter equation of state
Tyler Gorda, Oleg Komoltsev, Aleksi Kurkela
We demonstrate that ab-initio calculations in QCD at high densities offer significant and nontrivial information about the equation of state of matter in the cores of neutron stars…
How perturbative QCD constrains the Equation of State at Neutron-Star densities
Oleg Komoltsev, Aleksi Kurkela
We demonstrate in a general and analytic way how high-density information about the equation of state (EoS) of strongly interacting matter obtained using perturbative Quantum Chrom…
