GPU-accelerated Subcycling Time Integration with the Einstein Toolkit
Liwei Ji, Roland Haas, Yosef Zlochower +3
Adaptive Mesh Refinement (AMR) with subcycling in time enables different grid levels to advance using their own time steps, ensuring finer grids employ smaller steps for accuracy w…
Neutron star evolution by combining discontinuous Galerkin and finite volume methods
Ananya Adhikari, Wolfgang Tichy, Liwei Ji +1
We present here a new hybrid scheme that combines a discontinuous Galerkin (DG) method with compact finite volume (FV) and finite difference (FD) methods. The computational mesh is…
Relativistic gas accretion onto supermassive black Hole binaries from inspiral through merger
Lorenzo Ennoggi, Manuela Campanelli, Yosef Zlochower +8
Accreting supermassive black hole binaries are powerful multimessenger sources emitting both gravitational and EM radiation. Understanding the accretion dynamics of these systems a…
