Discovery of a radio emitting neutron star with an ultra-long spin period of 76 seconds. [PDF]
Nat Astron, 2022 The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emission is expected to cease.

Constraining neutron-star matter with microscopic and macroscopic collisions. [PDF]
Nature, 2022 Interpreting high-energy, astrophysical phenomena, such as supernova explosions or neutron-star collisions, requires a robust understanding of matter at supranuclear densities.

Neutron star merger remnants. [PDF]
Gen Relativ Gravit, 2020 Binary neutron star mergers observations are a unique way to constrain fundamental physics and astrophysics at the extreme. The interpretation of gravitational-wave events and their electromagnetic counterparts crucially relies on general-relativistic ...

Insights on Skyrme parameters from GW170817
Physics Letters B, 2019 The binary neutron-star merger event, GW170817, has cast a new light on nuclear physics research. Using a neutron-star model that includes a crust equation of state (EoS), we calculate the properties of a 1.4 solar-mass neutron star.

PSR J0952−0607: The Fastest and Heaviest Known Galactic Neutron Star [PDF]
Astrophysical Journal Letters, 2022 We describe Keck-telescope spectrophotometry and imaging of the companion of the “black widow” pulsar PSR J0952−0607, the fastest known spinning neutron star (NS) in the disk of the Milky Way. The companion is very faint at minimum brightness, presenting

Determination of the equation of state from nuclear experiments and neutron star observations [PDF]
Nature Astronomy, 2023 Nuclear experiments become the latest ‘messenger’ to help with unravelling the mysteries of neutron stars. Combining information from astronomical observations and laboratory experiments reveals how nucleons interact in both nuclei and stars. With recent

Cooling of neutron stars with quark-hadron continuity [PDF]
EPJ Web of Conferences, 2022 Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in

Constraints on the Dense Matter Equation of State and Neutron Star Properties from NICER’s Mass–Radius Estimate of PSR J0740+6620 and Multimessenger Observations [PDF]
Astrophysical Journal Letters, 2021 In recent years our understanding of the dense matter equation of state (EOS) of neutron stars has significantly improved by analyzing multimessenger data from radio/X-ray pulsars, gravitational wave events, and from nuclear physics constraints.
