To constrain the equation of state of cold dense matter, astrophysical measurements are
essential. These are mostly based on observations of neutron stars in the X-ray band, and …

Recent rapid progress in neutron-star (NS) observations offers great potential to constrain
the properties of strongly interacting matter under the most extreme conditions. In order to …

Interpreting high-energy, astrophysical phenomena, such as supernova explosions or
neutron-star collisions, requires a robust understanding of matter at supranuclear densities …

We report a revised analysis for the radius, mass, and hot surface regions of the massive
millisecond pulsar PSR J0740+ 6620, studied previously with joint fits to NICER and XMM …

Information on the phase structure of strongly interacting matter at high baryon densities can
be gained from observations of neutron stars and their detailed analysis. In the present work …

The symmetry energy and its density dependence are pivotal for many nuclear physics and
astrophysics applications, as they determine properties ranging from the neutron-skin …

With the aim of exploring the evidence for or against phase transitions in cold and dense
baryonic matter, the inference of the sound speed and equation of state for dense matter in …

We investigate the neutron star (NS) equation of state (EOS) by incorporating multi-
messenger data of GW170817, PSR J0030+ 0451, PSR J0740+ 6620, and state-of-the-art …

Astrophysical observations of neutron stars probe the structure of dense nuclear matter and
have the potential to reveal phase transitions at high densities. Most recent analyses are …

Magnetars are highly magnetized neutron stars, the formation mechanism of which is
unknown. Hot helium-rich stars with spectra dominated by emission lines are known as Wolf …
