Substructures in hydrodynamical cluster simulations

, 2009
The abundance and structure of dark matter subhalos has been analyzed extensively in recent studies of dark matter-only simulations, but comparatively little is known about the impact of baryonic physics on halo substructures.

Hydrodynamic Simulations of Convection [PDF]

International Astronomical Union Colloquium, 2002
Convection is one of the most problematic components of almost every model of a pulsating star. RR Lyrae stars, in particular, have a narrow convection zone at the outer layers, and a model without convection cannot get the red edge of the instability strip (see for example Kollath et al., 2000).In recent years, the common approach is to use non-local ...

Hydrodynamical Simulations of Galaxy Clusters with Galcons

, 2010
We present our recently developed {\em galcon} approach to hydrodynamical cosmological simulations of galaxy clusters - a subgrid model added to the {\em Enzo} adaptive mesh refinement code - which is capable of tracking galaxies within the cluster ...

Identification of gravity waves in hydrodynamical simulations

, 2004
The excitation of internal gravity waves by an entropy bubble oscillating in an isothermal atmosphere is investigated using direct two-dimensional numerical simulations.

Hydrodynamical Simulations of the IGM at High Mach Numbers [PDF]

, 2002
We present a new approach to doing Eulerian computational fluid dynamics that is designed to work at high Mach numbers encountered in hydrodynamical simulations of the IGM.

The origin of ICM enrichment in the outskirts of present-day galaxy clusters from cosmological hydrodynamical simulations [PDF]

, 2018
The uniformity of the intra-cluster medium (ICM) enrichment level in the outskirts of nearby galaxy clusters suggests that chemical elements were deposited and widely spread into the intergalactic medium before the cluster formation.

Hydrodynamic simulation of elliptic flow [PDF]

Nuclear Physics A, 1999
We use a hydrodynamic model to study the space-time evolution transverse to the beam direction in ultrarelativistic heavy-ion collisions with nonzero impact parameters. We focus on the influence of early pressure on the development of radial and elliptic flow.

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.

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?

The Astrophysical Journal Letters, 2023
Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.
