Joint Detection and Characterization of the Standing Accretion Shock Instability for Core-Collapse Supernovae with cWB XP
Vicente Sierra, Zidu Lin, Michelle Zanolin +3
The most sensitive to-date multimessenger detection of the standing accretion shock instability in real interferometric data is presented, which quantitatively identifies the prese…
Neutrino flavor instabilities in neutron star mergers with moment transport: Slow, fast, and collisional modes
Julien Froustey, Francois Foucart, Christian Hall +5
Determining where, when, and how neutrino flavor oscillations must be included in large-scale simulations of hot and dense astrophysical environments is an enduring challenge that…
Equation-of-state-informed pulse profile modeling
Mariska Hoogkamer, Nathan Rutherford, Daniela Huppenkothen +9
NICER has enabled mass-radius inferences for pulsars using pulse profile modeling (PPM), providing constraints on the equation of state (EOS) of cold, dense matter. To date, PPM an…
Gamma-Ray Burst Polarimetry with the POLAR and POLAR-2 missions
Nicolas De Angelis, Philipp Azzarello, Franck Cadoux +15
Gamma-Ray Bursts are among the most powerful and violent events in the Universe. Despite over half a century of observations of these transient sources, many open questions remain…
Investigating the Impact of Higher-Order Phase Transitions in Binary Neutron-Star Mergers
P. Hammond, A. Clevinger, M. Albino +10
In this paper we investigate quark deconfinement in neutrons stars and their mergers, focusing on the effects of higher orders for the phase transition between hadronic and quark m…
Magnetic Flux Emergence in Binary Neutron Star Remnants
Jacob Fields, David Radice, Peter Hammond
Using high-resolution AthenaK simulations of a twisted toroidal flux tube, we study the flux emergence of magnetic structures in the shear layer of a hot massive neutron star typic…
Recurring region for neutron-star observables
Alexander Clevinger, Zidu Lin, Milena Albino +3
In this letter, we report a novel, somewhat analytical way to produce equations of state (EOSs) that generate particular values of neutron star mass, radius, and tidal deformabilit…
Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed
M. Pillas, S. Antier, K. Ackley +78
Neutron star-black hole (NSBH) mergers, detectable via their gravitational-wave (GW) emission, are expected to produce kilonovae (KNe). Four NSBH candidates have been identified an…
Advection Algorithms for Quantum Neutrino Moment Transport
Evan Grohs, Sherwood Richers, Julien Froustey +3
Neutrino transport in compact objects is an inherently challenging multi-dimensional problem. This difficulty is compounded if one includes flavor transformation -- an intrinsicall…
A Two-Week Monitoring Campaign on Mrk 421
W. Peter Maksym, Ioannis Liodakis, M. Lynne Saade +153
X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the firs…
Influence of neutrino-electron scattering and neutrino-pair annihilation on hypermassive neutron star
Patrick Chi-Kit Cheong, Francois Foucart, Harry Ho-Yin Ng +4
We investigate the influence of inelastic neutrino microphysics in general-relativistic magnetohydrodynamics simulations of a hypermassive neutron star. In particular, we include s…
Probing fermionic asymmetric dark matter cores using global neutron star properties
Nathan Rutherford, Chanda Prescod-Weinstein, Anna Watts
It is possible for asymmetric dark matter (ADM) to accumulate in neutron star interiors and affect their global properties. Considering the effects of this accumulation, neutron st…
