The Cosmological Simulation Code OpenGadget3 - Implementation of Self-Interacting Dark Matter
Moritz S. Fischer, Marc Wiertel, Cenanda Arido +7
Dark matter (DM) could be subject to non-gravitational self-interactions which is relevant to resolve potential problems of cold DM on small scales. Their impact on astrophysical o…

General Implicit Runge-Kutta Integrators for Multifluid Gas-Dust Aerodynamic Drag
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
The integration of aerodynamic drag is a fundamental step in simulating dust dynamics in hydrodynamical simulations. We propose a novel integration scheme, designed to be compatibl…

Modeling dust dynamics in OpenGadget3 -- I. SPH implementation of the One-Fluid model
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
Dust dynamics plays a critical role in astrophysical processes and has been modeled in hydrodynamical simulations using various approaches. Among particle-based methods like Smooth…
