The mirror twin Higgs model is a candidate for (strongly-interacting) complex dark matter,
which mirrors SM interactions with heavier quark masses. A consequence of this model are …

We present a novel relativistic density-functional approach to modeling quark matter with a
mechanism to mimic confinement. The quasiparticle treatment of quarks provides their …

We explore the connection between the stiffness of a hadronic equation of state (EoS) with a
sharp phase transition to quark matter to its tidal deformability. For this we employ a …

The observations of PSR J0952-0607 (M= 2. 35− 0.17+ 0.17 M⊙) and the second object in
the GW190814 event (M= 2. 59− 0.09+ 0.08 M⊙) indicate the possible existence of …

The tidal deformability and the radius of neutron stars are observables, which have been
used to constrain the neutron star equation of state and explore the composition in neutron …

Transition of a compact star into the third family for an equation of state (EoS) featuring mass
twins is considered. The energy released at a baryon number conserving the transition of …

We examine which first order phase transitions are consistent with today's astrophysical
constraints. In particular, we explore how a well-constrained mass-radius data point would …

Neutron stars are expected to have a tight relation between their moment of inertia (I), tidal
deformability (λ, which is related to the Love number), and rotational mass quadrupole …

GW170817 has provided valuable constraints on the equations of state of merging binary
neutron stars, which can be considered as the most probable candidate for the source of …

Although it is conjectured that a phase transitions from hadronic to deconfined quark matter
in the ultrahigh-density environment of neutron stars (NS), the nature of phase transition …
