Asymmetric eROSITA bubbles as the evidence of a circumgalactic medium wind
Nature Communications, 2023 The origins of the pair of X-ray bubbles, called eROSITA bubbles (eRBs), detected in the halo of Milky Way are debated. Here, the authors show hydrodynamical simulations suggesting circumgalactic medium wind model can explain asymmetric eRBs.

Hydrodynamical Simulations of Recollimation Shocks within Relativistic Astrophysical Jets
Galaxies, 2018 Astrophysical jets launched from active galactic nuclei can remain tightly collimated over large distances due, in part, to recollimation shocks.

Hydrodynamical Simulations of Nuclear Rings in Barred Galaxies
, 2015 Dust lanes, nuclear rings, and nuclear spirals are typical gas structures in the inner region of barred galaxies. Their shapes and properties are linked to the physical parameters of the host galaxy.

Simulations of the Origin and Fate of the Galactic Center Cloud G2 [PDF]
, 2012 We investigate the origin and fate of the recently discovered gas cloud G2 close to the Galactic Center. Our hydrodynamical simulations focussing on the dynamical evolution of the cloud in combination with currently available observations favor two ...

General Implicit Runge–Kutta Integrators for Multifluid Gas–Dust Aerodynamic Drag
The Astrophysical JournalThe integration of aerodynamic drag is a fundamental step in simulating dust dynamics in hydrodynamical simulations. We propose a novel integration scheme, designed to be compatible with Strang splitting techniques, which allows for the straightforward ...

Numerical simulation of the dynamics of sedimentary river beds with a stochastic Exner equation
ESAIM: Proceedings and Surveys, 2015 At the scale of a river reach, the dynamics of the river bed is typically modelled by Exner equation (conservation of the solid mass) with an empirical solid flux of transported sediments, which is a simple deterministic algebraic ...

Hydrodynamical Simulations of the Lyman Alpha Forest: Model Comparisons [PDF]
, 1999 We investigate the properties of the Lyman alpha forest as predicted by numerical simulations for a range of currently viable cosmological models. This is done in order to understand the dependencies of the forest on cosmological parameters.

Scalability of Hydrodynamic Simulations
, 2009 Many hydrodynamic processes can be studied in a way that is scalable over a vastly relevant physical parameter space. We systematically examine this scalability, which has so far only briefly discussed in astrophysical literature. We show how the scalability is limited by various constraints imposed by physical processes and initial conditions.

Merger-tree-based Galaxy Matching: A Comparative Study across Different Resolutions
The Astrophysical JournalWe introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their subhalo merger tree. With this tool, we conduct a study of resolution biases
