Numerical convergence of hydrodynamical simulations of galaxy formation: the abundance and internal structure of galaxies and their cold dark matter haloes [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We address the issue of numerical convergence in cosmological smoothed particle hydrodynamics simulations using a suite of runs drawn from the eagle project.

Robustness of a high-resolution central scheme for hydrodynamic simulations in full general relativity [PDF]

, 2005
A recent paper by Lucas-Serrano et al. indicates that a high-resolution central (HRC) scheme is robust enough to yield accurate hydrodynamical simulations of special relativistic flows in the presence of ultrarelativistic speeds and strong shock waves ...

The BAHAMAS project: Calibrated hydrodynamical simulations for large-scale structure cosmology [PDF]

, 2016
The evolution of the large-scale distribution of matter is sensitive to a variety of fundamental parameters that characterise the dark matter, dark energy, and other aspects of our cosmological framework.

An observational test for star formation prescriptions in cosmological hydrodynamical simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2018
State-of-the-art cosmological hydrodynamical simulations of galaxy formation have reached the point at which their outcomes result in galaxies with ever more realism. Still, the employed sub-grid models include several free parameters such as the density

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.

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.

Radiation hydrodynamical simulations of eruptive mass loss from progenitors of Type Ibn/IIn supernovae [PDF]

Astronomy & Astrophysics, 2019
Context. Observations suggest that some massive stars experience violent and eruptive mass loss associated with significant brightening that cannot be explained by hydrostatic stellar models.

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 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 ...

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.
