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…
The Quiescent Sloshing Core of Abell 496 with XRISM
Angie Veronica, Thomas H. Reiprich, Naomi Ota +9
Gas motions provide insight into the dynamical history and physical processes within galaxy clusters. We investigate the kinematics of the ICM in the core of A496, a nearby, X-ray…
OpenGadget3 GPU solver tests
A. Ragagnin, G. S. Karademir, F. Groth +6
We present an in-depth evaluation of the scalability and accuracy of the GPU porting of the N-body code for hydrodynamic cosmological simulations \og. While technical details of ou…
Turbulence in Simulated Local Cluster Analogs: One-to-one comparisons between SLOW and XRISM/Hitomi
Frederick Groth, Milena Valentini, Benjamin A. Seidel +4
The XRISM Resolve X-ray spectrometer allows to gain detailed insight into gas motions of the intra cluster medium (ICM) of galaxy clusters. Current simulation studies focus mainly…
N-body simulations of dark matter-baryon interactions
Moritz S. Fischer, Klaus Dolag, Mathias Garny +3
Dark matter (DM) particles can interact with particles of the standard model. Although there are a number of constraints derived from direct and indirect detection experiments, the…
Turbulent Pressure Support in Galaxy Clusters -- Impact of the Hydrodynamical Solver
Frederick Groth, Milena Valentini, Ulrich P. Steinwandel +2
The amount of turbulent pressure in galaxy clusters is still debated, especially as for the impact of the dynamical state and the hydro-method used for simulations. We study the tu…
Vortex-p: a Helmholtz-Hodge and Reynolds decomposition algorithm for particle-based simulations
David Vallés-Pérez, Susana Planelles, Vicent Quilis +3
Astrophysical turbulent flows display an intrinsically multi-scale nature, making their numerical simulation and the subsequent analyses of simulated data a complex problem. In par…
The Cosmological Simulation Code OpenGadget3 -- Implementation of Meshless Finite Mass
Frederick Groth, Ulrich P. Steinwandel, Milena Valentini +1
Subsonic turbulence plays a major role in determining properties of the intra cluster medium (ICM). We introduce a new Meshless Finite Mass (MFM) implementation in OpenGadget3 and…
