We study the predicted sub-mm emission from massive galaxies in a Lambda-CDM universe, using hydrodynamic cosmological simulations. Assuming that most of the emission from newly formed stars is absorb...
Metal enrichment of the intergalactic medium in cosmological simulations
intergalactic medium formation starburst
2014/12/26
Observations have established that the diffuse intergalactic medium (IGM) at z ~ 3 is enriched to ~10-2.5 solar metallicity and that the hot gas in large clusters of galaxies (ICM) is enriched to - Z ...
We use hydrodynamic simulations to examine how the baryonic components of galaxies are assembled, focusing on the relative importance of mergers and smooth accretion in the formation of ~L* systems. I...

Recently Ménard et al. (hereafter MSFR) detected a subtle but systematic change in the mean colour of quasars as a function of their projected separation from foreground galaxies, extending to comovin...
Early Black Holes in Cosmological Simulations: Luminosity Functions and Clustering Behaviour
quasars: general — galaxies: active — black hole physics — methods: numerical — galaxies: haloes
2011/9/29
We examine predictions for the quasar luminosity functions (QLF) and quasar clustering at high redshift (z > 4.75) using MassiveBlack, our new hydrodynamic cosmological simulation which includes a sel...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies: haloes cosmology: theory methods: N-body simulations
2011/9/26
We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...

Short-lived star-forming giant clumps in cosmological simulations of z~2 disks
galaxies evolution— galaxies formation— galaxies high-redshift—galaxies structure
2010/11/9
Many observed massive star-forming z ≈ 2 galaxies are large disks that exhibit irregular morphologies, with ≈ 1 kpc, ≈ 108-10M⊙ clumps. We present high-resolution cosmological SPH simulations that zoo...

TreePM Code for Two-Dimensional Cosmological Simulations
Gravitation methods numerical cosmology large scale structure of the universe
2009/5/14
We describe the two-dimensional TreePM method in this paper. The 2d TreePM code is an accurate and efficient technique to carry out large two-dimensional N-body simulations in cosmology. This hybri...
