IllinoisGRMHD: Recent Developments and Future Plans

We have recently added support for finite-temperature, microphysical equations of state and neutrino physics (via a leakage scheme) to IllinoisGRMHD, an open-source Einstein Toolkit module that solves the General Relativistic Magnetohydrodynamics equations. First, we describe the two new open-source NRPy+-based codes that implement these new features: NRPyEOS and NRPyLeakage. Second, we present results of magnetized BNS simulations that leverage these improvements. Third, we discuss the modularization of these new features and their implementation in the open-source, infrastructure-agnostic General Relativistic Hydrodynamic Library (GRHayL), which is currently under development. Finally, we report on ongoing efforts, such as a new M1 closure scheme for neutrino radiation transport.
