ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves
Tim Dietrich, Tanja Hinderer, Micaela Oertel +40
Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…
Probing neutron star interiors and the properties of cold ultra-dense matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…
Differentially rotating neutron stars with dark matter cores
Lorenzo Cipriani, Violetta Sagun, Kalin V. Staykov +2
Dark matter is expected to accumulate inside neutron stars, modifying the structure of isolated stars and influencing both the dynamics of binary mergers and the evolution of the r…
Color-superconducting quarkyonic matter
Christoph Gärtlein, Oleksii Ivanytskyi, Violetta Sagun +1
We explore the role of color superconductivity in quarkyonic matter under the conditions of color and electric neutrality at - and strong equilibrium, as relevant for neutron st…
Numerical Relativity Simulations of Dark Matter Admixed Binary Neutron Stars
Edoardo Giangrandi, Hannes R. Rüter, Nina Kunert +7
Binary neutron star mergers provide insight into strong-field gravity and the properties of ultra-dense nuclear matter. These events offer the potential to search for signatures of…
Rapidly spinning dark matter-admixed neutron stars
Lorenzo Cipriani, Edoardo Giangrandi, Violetta Sagun +2
Millisecond pulsars, representing the older neutron star population, are believed to have undergone a prolonged period of dark matter accumulation, resulting in a higher dark matte…
