Large-scale mass distribution in the Illustris simulation
Observations at low redshifts thus far fail to account for all of the baryons expected in the Universe according to cosmological constraints. A large fraction of the baryons presumably resides in a thin and warm–hot medium between the galaxies, where they are difficult to observe due to their low densities and high temperatures. Cosmological simulations of structure formation can be used to ver...
متن کاملThe star formation main sequence and stellar mass assembly of galaxies in the Illustris simulation
Understanding the physical processes that drive star formation is a key challenge for galaxy formation models. In this paper, we study the tight correlation between the star formation rate (SFR) and stellar mass of galaxies at a given redshift, how halo growth influences star formation, and star formation histories of individual galaxies. We study these topics using Illustris, a state-of-the-ar...
متن کاملThe mass profile of the Milky Way to the virial radius from the Illustris simulation
We use particle data from the Illustris simulation, combined with individual kinematic constraints on the mass of the Milky Way (MW) at specific distances from the Galactic Centre, to infer the radial distribution of the MW’s dark matter halo mass. Our method allows us to convert any constraint on the mass of the MWwithin a fixed distance to a full circular velocity profile to the MW’s virial r...
متن کاملParallel Simulation of Large-scale Water Distribution Systems
This paper describes the development of parallel algorithms for the processing of telemetry data in the specific context of water distribution networks. Today’s increasing complexity of such systems, together with the requirement for smaller discretisation intervals means that the task of simulating large-scale water distribution networks frequently outgrows the computational power of economica...
متن کاملLarge-Scale Simulation Platform
A large-scale simulation platform that includes various simulation engines and is intended for application in a variety of domains is considered. Conceptual design of platform and its implementation are described. The platform supports model-based software development and uses structural synthesis of programs for translation of declarative specification of simulation problems into executable co...
