Rapid Localization of Gravitational Wave Sources from Compact Binary Coalescences Using Deep Learning

open access: yesThe Astrophysical Journal, 2023
The mergers of neutron star–neutron star and neutron star–black hole binaries (NSBHs) are the most promising gravitational wave (GW) events with electromagnetic (EM) counterparts.

Neutron skins and neutron stars [PDF]

open access: yesAIP Conference Proceedings, 2013
The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

Insights on Skyrme parameters from GW170817

open access: yesPhysics 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.

Superfluid phases of triplet pairing and rapid cooling of the neutron star in Cassiopeia A

open access: yesPhysics Letters B, 2015
In a simple model it is demonstrated that the neutron star surface temperature evolution is sensitive to the phase state of the triplet superfluid condensate.

Letter to Nature: An ultra-relativistic outflow from a neutron star accreting gas from a companion. [PDF]

open access: yes, 2004
Collimated relativistic outflows—also known as jets—are amongst the most energetic phenomena in the Universe. They are associated with supermassive black holes in distant active galactic nuclei1, accreting stellar-mass black holes and neutron stars in ...

Nonparametric Model for the Equations of State of a Neutron Star from Deep Neural Network

open access: yesThe Astrophysical Journal, 2023
It is of great interest to understand the equation of state (EOS) of the neutron star, whose core includes highly dense matter. However, there are large uncertainties in the theoretical predictions for the EOS of a neutron star. It is useful to develop a

Mirror neutron stars

open access: yesPhysical Review D, 2022
The fundamental nature of dark matter is entirely unknown. A compelling candidate is Twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces. This predicts mirror neutron stars made entirely of mirror nuclear matter. We find their structure using realistic equations of state, robustly modified based on first-

Neutron-mirror neutron mixing and neutron stars [PDF]

open access: yesThe European Physical Journal C, 2021
AbstractThe oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark stars $$n-n'$$
