Numerical simulations of neutron star–neutron star and neutron star–black hole binaries
play an important role in our ability to model gravitational-wave and electromagnetic signals …

Compact binary mergers involving neutron stars can eject a fraction of their mass to space.
Being extremely neutron rich, this material undergoes rapid neutron capture …

We present a new moment-based energy-integrated neutrino transport code for neutron star
merger simulations in general relativity. In the merger context, ours is the first code to include …

The 2017 detection of the inspiral and merger of two neutron stars in gravitational waves
and gamma rays was accompanied by a quickly reddening transient. Such a transient was …

In order to extract maximal information from neutron-star merger signals, both gravitational
and electromagnetic, we need to ensure that our theoretical models/numerical simulations …

We present a coherent study of the impact of neutrino interactions on the r-process element
nucleosynthesis and the heating rate produced by the radioactive elements synthesized in …

We model a compact black hole-accretion disk system in the collapsar scenario with full
transport, frequency dependent, general relativistic radiation magnetohydrodynamics. We …

We have added support for realistic, microphysical, finite-temperature equations of state
(EOS) and neutrino physics via a leakage scheme to illinoisgrmhd, an open-source GRMHD …

We present a new method for the numerical solution of the radiative-transfer equation (RTE)
in multidimensional scenarios commonly encountered in computational astrophysics. The …

We provide a systematic description of the steps necessary–and of the potential pitfalls to be
encountered–when implementing a two-moment scheme within an implicit–explicit (IMEX) …
