QED cross sections in strong magnetic fields

Olavi Kiuru, Joonas Nättilä, Risto Paatelainen +1

The magnetospheres of magnetars, a class of highly magnetized neutron stars, host magnetic fields exceeding the Schwinger limit, where Quantum Electrodynamics (QED) becomes nonline…

Strong model-agnostic constraints for twin-star solutions

Sofia Blomqvist, Christian Ecker, Tyler Gorda +1

We perform a model-agnostic Bayesian analysis of the neutron-star-matter equation of state (EoS), using known ab-initio constraints and astrophysical observations to limit its beha…

Recent advances in perturbative QCD at high density

Pablo Navarrete, Aleksi Vuorinen

In these conference proceedings, we discuss recent progress in high-order perturbative studies of the thermodynamic and transport properties of dense quark matter. Special emphasis…

Dense Matter in Neutron Stars with eXTP

Ang Li, Anna L. Watts, Guobao Zhang +82

In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…

Quark matter at four loops: hardships and how to overcome them

A. Kärkkäinen, P. Navarrete, M. Nurmela +3

Knowledge of the pressure of cold and dense quark matter (QM) is known to significantly constrain the equation of state of neutron-star matter, a quantity playing a key role in dec…

Estimate for the bulk viscosity of strongly coupled quark matter using perturbative QCD and holography

Jesús Cruz Rojas, Tyler Gorda, Carlos Hoyos +6

Modern hydrodynamic simulations of core-collapse supernovae and neutron-star mergers require knowledge not only of the equilibrium properties of strongly interacting matter, but al…
