Ring galaxies in the EAGLE hydrodynamical simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of 100 cMpc on a side, to identify and characterize these systems through cosmic time.

Low-surface-brightness Galaxies are Missing in the Observed Stellar Mass Function
The Astrophysical Journal, 2023 We investigate the impact of the surface-brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using galaxy catalogs generated from the Horizon Run 5 ( HR5 ) simulation.

Hydrodynamical simulations of detonations in superbursts [PDF]
Computer Physics Communications, 2008 A new hydrodynamical algorithm to study astrophysical detonations is presented. A prime motivation of this development is the description of a carbon detonation in conditions relevant to superbursts, which are thought to result from the propagation of a detonation front around the surface of a neutron star in the carbon layer underlying the atmosphere.

Hydrodynamic simulations with the Godunov smoothed particle hydrodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We present results based on an implementation of the Godunov smoothed particle hydrodynamics (GSPH), originally developed by Inutsuka, in the gadget-3 hydrodynamic code. We first review the derivation of the GSPH discretization of the equations of moment and energy conservation, starting from the convolution of these equations with the interpolating ...

Mesoscale simulations of hydrodynamic squirmer interactions [PDF]
Physical Review E, 2010 The swimming behavior of self-propelled microorganisms is studied by particle-based mesoscale simulations. The simulation technique includes both hydrodynamics and thermal fluctuations that are both essential for the dynamics of microswimmers. The swimmers are modeled as squirmers, i.e., spherical objects with a prescribed tangential surface velocity ...

The Mass Fractionation of Helium in the Escaping Atmosphere of HD 209458b
The Astrophysical Journal, 2023 The absorption signals of metastable He in HD 209458b and several other exoplanets can be explained via an escaping atmosphere model with a subsolar He/H ratio. The low abundance of helium can be a result of planet formation if there is a small amount of

The Athena++ Adaptive Mesh Refinement Framework: Multigrid Solvers for Self-gravity
The Astrophysical Journal Supplement Series, 2023 We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-gravity.

Full hydrodynamic simulation of GaAs MESFETs [PDF]
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2004 AbstractA finite difference upwind discretization scheme in two dimensions is presented in detail for the transient simulation of the highly coupled non‐linear partial differential equations of the full hydrodynamic model, providing thereby a practical engineering tool for improved charge carrier transport simulations at high electric fields and ...
