The OpenGadget3 Code for Cosmological Simulations
Klaus Dolag, Geray S. Karademir, Luca Tornatore +28
We present the public release of OpenGadget3 (OG3), a substantially extended and re-organised version of the widely used Gadget-2/3 family of cosmological simulation codes. Since G…
Cutting with precision -- Leveraging Collapse Volumes to generate the next generation of zoom-in initial conditions
Benjamin Seidel, Klaus Dolag, Jenny G. Sorce
Astrophysical processes happen across a wide range of scales. This poses a significant challenge from the perspective of modeling these processes. Modern cosmological simulations a…
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…
