Properties of galaxies reproduced by a hydrodynamic simulation [PDF]
Nature, 2014 Previous simulations of the growth of cosmic structures have broadly reproduced the 'cosmic web' of galaxies that we see in the Universe, but failed to create a mixed population of elliptical and spiral galaxies due to numerical inaccuracies and incomplete physical models.

The El Gordo Galaxy Cluster Challenges ΛCDM for Any Plausible Collision Velocity
The Astrophysical Journal, 2023 El Gordo (ACT-CL J0102-4915) is an extraordinarily large and bright galaxy cluster collision. In a previous study, we found that El Gordo is in 6.2 σ tension with the Λ cold dark matter (ΛCDM) standard model when assuming the nominal mass and infall ...

Hydrodynamic and magnetohydrodynamic simulations of wire turbulence [PDF]
High Energy Density Physics, 2019 We report on simulations of laboratory experiments in which magnetized supersonic flows are driven through a wire mesh. The goal of the study was to investigate the ability of such a configuration to generate supersonic, MHD turbulence. We first report on the morphological structures that develop in both magnetized and non-magnetized cases.

Assessing subhalo finders in cosmological hydrodynamical simulations [PDF]
Cosmological simulations are essential for inferring cosmological and galaxy population properties based on forward-modelling, but this typically requires finding the population of (sub)haloes and galaxies that they contain.

Bars in hydrodynamical cosmological simulations [PDF]
, 2012 International audienceWe study the properties of two bars formed in fully cosmological hydrodynamical simulations of the formation of Milky Way-mass galaxies. In one case, the bar formed in a system with disc, bulge and halo components, and is relatively

3D Hydrodynamical Simulations of a Galactic Fountain [PDF]
International Astronomical Union Colloquium, 1997 AbstractGalactic fountains are thought to be responsible for the formation of the observed intermediate and high velocity clouds in the Galactic halo. Threedimensional simulations have been carried out to determine the evolution of the disk gas as it enters the fountain, cools and returns to the Galactic disk. The descending cold gas, headed by a shock,

Hydrodynamic simulations of self-phoretic microswimmers [PDF]
Soft Matter, 2014 A mesoscopic hydrodynamic model to simulate synthetic self-propelled Janus particles which is thermophoretically or diffusiophoretically driven is here developed. We first propose a model for a passive colloidal sphere which reproduces the correct rotational dynamics together with strong phoretic effect.
