Late-time emission-line profiles from kilonova models

S. A. Sim, O. Just, Z. Xiong +10

Numerical simulations suggest that neutron star mergers eject material with complex, non-spherical density and composition distributions. Here we use two-dimensional configurations…

Self-consistent 3D radiative transfer for kilonovae: directional spectra from merger simulations

Luke J. Shingles, Christine E. Collins, Vimal Vijayan +7

We present three-dimensional radiative transfer calculations for the ejecta from a neutron star merger that include line-by-line opacities for tens of millions of bound-bound trans…

Helium as an Indicator of the Neutron-Star Merger Remnant Lifetime and its Potential for Equation of State Constraints

Albert Sneppen, Oliver Just, Andreas Bauswein +9

The time until black hole formation in a binary neutron-star (NS) merger contains invaluable information about the nuclear equation of state (EoS) but has thus far been difficult t…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…

Fast neutrino flavor conversions in a supernova: Emergence, evolution, and effects

Zewei Xiong, Meng-Ru Wu, Manu George +4

Fast flavor conversions (FFCs) of neutrinos, which can occur in core-collapse supernovae (CCSNe), are multiangle effects. They depend on the angular distribution of the neutrino's…

Luminosity predictions for the first three ionisation stages of W, Pt and Au to probe potential sources of emission in kilonova

M. McCann, L. P. Mulholland, Z. Xiong +7

A large number of R-matrix calculations of electron impact excitation for heavy elements (Z > 70) have been performed in recent years for applications in fusion and astrophysics re…
