Hot and Cooled baryons in SPH simulations of galaxy clusters: physics and numerics
We discuss an extended set of Tree+SPH simulations of the formation of clusters of galaxies, with the goal of investigating the interplay between numerical resolution effects and star– formation/feedback processes. Our simulations were all carried out in a concordance ΛCDM cosmology and include radiative cooling, star formation, and energy feedback from galactic winds. The simulated clusters sp...
متن کاملPhysical viscosity in smoothed particle hydrodynamics simulations of galaxy clusters
Most hydrodynamical simulations of galaxy cluster formation carried out to date have tried to model the cosmic gas as an ideal, inviscid fluid, where only a small amount of (unwanted) numerical viscosity is present, arising from practical limitations of the numerical method employed, and with a strength that depends on numerical resolution. However, the physical viscosity of the gas in hot gala...
متن کاملMomentum transfer across shear flows in Smoothed Particle Hydrodynamic simulations of galaxy formation
We investigate the evolution of angular momentum in Smoothed Particle Hydrodynamic (SPH) simulations of galaxy formation, paying particular attention to artificial numerical effects. We find that a cold gas disc forming in an ambient hot gas halo receives a strong hydrodynamic torque from the hot gas. By splitting the hydrodynamic force into artificial viscosity and pressure gradients, we find ...
متن کاملHot Gas in Galaxy Clusters: Theory and Simulations
— We review the theory of the formation of galaxy clusters and discuss their role as cosmological probes. We begin with the standard cosmological framework where we discuss the origin of the CDM matter power spectrum and the growth of density fluctuations in the linear regime. We then summarize the spherical top-hat model for the nonlinear growth of fluctuations from which scaling relations and...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
