Distinct neutrino signatures and onset condition of quark deconfinement in accretion-induced collapse of white dwarfs
Juno C. L. Chan, Harry Ho-Yin Ng, Patrick Chi-Kit Cheong
We present the first general relativistic, neutrino-radiation hydrodynamics simulations of accretion-induced collapse (AIC) extending to seconds after core bounce, using realistic…
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…
cymyc -- Calabi-Yau Metrics, Yukawas, and Curvature
Per Berglund, Giorgi Butbaia, Tristan Hübsch +4
We introduce \texttt{cymyc}, a high-performance Python library for numerical investigation of the geometry of a large class of string compactification manifolds and their associate…
First Measurement of Near- and Sub-Threshold Photoproduction off Nuclei
J. R. Pybus, L. Ehinger, T. Kolar +65
We report on the first measurement of photoproduction from nuclei in the photon energy range of to GeV, extending above and below the photoproduction threshold in…
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…
Non-conservation of Lepton Numbers in the Neutrino Sector Could Change the Prospects for Core Collapse Supernova Explosions
Anna M. Suliga, Patrick Chi-Kit Cheong, Julien Froustey +5
We show that interactions violating the conservation of lepton numbers in the neutrino sector could significantly alter the standard low entropy picture for the pre-supernova colla…
Quantum Closures for Neutrino Moment Transport
James P. Kneller, Julien Froustey, Evan B. Grohs +3
A computationally efficient method for calculating the transport of neutrino flavor in simulations is to use angular moments of the neutrino one-body reduced density matrix, i.e.,…
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…
Symmetry groups and invariant solutions of plane Poiseuille flow
Pratik P. Aghor, John F. Gibson
Equilibrium, traveling-wave, and periodic-orbit solutions of the Navier-Stokes equations provide a promising avenue for investigating the structure, dynamics, and statistics of tra…
Rapidly Rotating Wall-Mode Convection
Geoffrey M. Vasil, Keaton J. Burns, Daniel Lecoanet +3
In the rapidly rotating limit, we derive a balanced set of reduced equations governing the strongly nonlinear development of the convective wall-mode instability in the interior of…
General-relativistic resistive-magnetohydrodynamics simulations of self-consistent magnetized rotating neutron stars
Patrick Chi-Kit Cheong, Antonios Tsokaros, Milton Ruiz +4
We present the first general-relativistic resistive magnetohydrodynamics simulations of self-consistent, rotating neutron stars with mixed poloidal and toroidal magnetic fields. Sp…
Measurement of the nucleon spin structure functions for 0.01<<1 GeV using CLAS
A. Deur, S. E. Kuhn, M. Ripani +147
The spin structure functions of the proton and the deuteron were measured during the EG4 experiment at Jefferson Lab in 2006. Data were collected for longitudinally polarized elect…
Asymptotic-state prediction for fast flavor transformation in neutron star mergers
Sherwood Richers, Julien Froustey, Somdutta Ghosh +2
Neutrino flavor instabilities appear to be omnipresent in dense astrophysical environments, thus presenting a challenge to large-scale simulations of core-collapse supernovae and n…

Francesco Grippa, Aviral Prakash, Domenico Logoteta +2
We perform fully general-relativistic simulations of binary strange star mergers considering two different approaches for thermal effects. The first uses a cold equation of state (…
Toward Reliable Ad-hoc Scientific Information Extraction: A Case Study on Two Materials Datasets
Satanu Ghosh, Neal R. Brodnik, Carolina Frey +4
We explore the ability of GPT-4 to perform ad-hoc schema based information extraction from scientific literature. We assess specifically whether it can, with a basic prompting appr…
Three-flavor, Full Momentum Space Neutrino Spin Oscillations in Neutron Star Mergers
Henry Purcell, Sherwood Richers, Amol V. Patwardhan +1
In the presence of anisotropic neutrino and antineutrino fluxes, the quantum kinetic equations drive coherent oscillations in neutrino helicity, frequently referred to as spin osci…
Stability of hypermassive neutron stars with realistic rotation and entropy profiles
Nishad Muhammed, Matthew D. Duez, Pavan Chawhan +7
