Cosmological hydrodynamics with adaptive mesh refinement - A new high resolution code called RAMSES
A new N-body and hydrodynamical code, called RAMSES, is presented. It has been designed to study structure formation in the universe with high spatial resolution. The code is based on Adaptive Mesh
Cold streams in early massive hot haloes as the main mode of galaxy formation
‘stream-fed galaxies’ are reported, formed from steady, narrow, cold gas streams that penetrate the shock-heated media of massive dark matter haloes and keep the rotating disk configuration intact, although turbulent and broken into giant star-forming clumps that merge into a central spheroid.
Fundamental differences between SPH and grid methods
We have carried out a comparison study of hydrodynamical codes by investigating their performance in modelling interacting multiphase fluids. The two commonly used techniques of grid and smoothed
Euclid Definition Study Report
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate the
Dancing in the dark: galactic properties trace spin swings along the cosmic web
A large-scale hydrodynamical cosmological simulation, Horizon-AGN , is used to investigate the alignment between the spin of galaxies and the large-scale cosmic filaments above redshift one. The
Bimodal gas accretion in the Horizon–MareNostrum galaxy formation simulation
The physics of diffuse gas accretion and the properties of the cold and hot modes of accretion on to proto-galaxies between z= 2 and 5.4 is investigated using the large cosmological simulation
The history of the baryon budget. Cosmic logistics in a hierarchical universe
Using a series of high-resolution N-body hydrodynamical numerical simulations, we investigate several scenarios for the evolution of the baryon budget in galactic halos. We derive individual halo
Morphological Quenching of Star Formation: Making Early-Type Galaxies Red
We point out a natural mechanism for quenching of star formation in early-type galaxies (ETGs). It automatically links the color of a galaxy with its morphology and does not require gas consumption,
ISM properties in hydrodynamic galaxy simulations: turbulence cascades, cloud formation, role of gravity and feedback
We study the properties of ISM substructure and turbulence in hydrodynamic (AMR) galaxy simulations with resolutions up to 0.8 pc and 5 � 10 3 M� . We analyse the power spectrum of the density
A high order Godunov scheme with constrained transport and adaptive mesh refinement for astrophysical magnetohydrodynamics
Aims. In this paper, we present a new method to perform numerical simulations of astrophysical MHD flows using the Adaptive Mesh Refinement framework and Constrained Transport. Methods. The algorithm
