We present a semi-analytic treatment of galactic winds within high-resolution, large-scale cosmological N-body simulations of a A cold dark matter (ACDM) universe. The evolution of winds is investigated by following the expansion of supernova-driven superbubbles around the several hundred thousand galaxies that form in an approximately spherical region of space with diameter 52 h -1 Mpc and mean density close to the mean density of the universe. We focus our attention on the impact of winds on… 
Galactic winds in cosmological simulations of the circumgalactic medium
We explore new observationally-constrained sub-resolution models of galactic outflows and investigate their impact on the circumgalactic medium (CGM) in the redshift range z = 2 4. We perform
Constrained semi-analytical models of galactic outflows
We present semi-analytic models of galactic outflows that are constrained by available observations on high-redshift star formation and reionization. Galactic outflows are modelled in a manner akin
We investigate the large-scale influence of outflows from active galactic nuclei (AGNs) in enriching the intergalactic medium (IGM) with metals in a cosmological context. We combine cosmological
Cosmological Simulations of the Intergalactic Medium Evolution. II. Galaxy Model and Feedback
We present a semi-analytical model designed to be included in large-scale cosmological simulations to treat the evolution of galaxies. The goal of this paper is to test our model to make sure that it
Towards a new modelling of gas flows in a semi-analytical model of galaxy formation and evolution
We present an extended version of the semi-analytical model, GalICS. Like its predecessor, eGalICS applies a post-treatment of the baryonic physics on pre-computed dark-matter merger trees extracted
On the onset of galactic winds in quiescent star forming galaxies
Context. The hierarchical model of galaxy formation, despite its many successes, still overpredicts the baryons fraction locked in galaxies as a condensed phase. The efficiency of supernovae
Magnetic Field Seeding by Galactic Winds
The origin of intergalactic magnetic fields is still a mystery and several scenarios have been proposed so far: among them, primordial phase transitions, structure-formation shocks and galactic
How do galactic winds affect the Lyα forest
ABSTRACT We investigatethe effect ofgalacticwinds onthe Lyα forestin cosmologicalsimulationsof structure and galaxy formation. We combine high resolution N-body simulationsof the evolution of the dark
The impact of galactic winds from Lyman-break galaxies on the intergalactic medium
An excess of sight-lines close to Lyman-break galaxies (LBGs) with little or no absorption in QSO absorption spectra has been reported and has been interpreted as the effect of galactic winds on the
A dynamical model of supernova feedback: gas outflows from the interstellar medium
In this Chapter, a dynamical model of supernova feedback which follows the evolution of bubbles driven by supernovae in a multi-phase interstellar medium (ISM) is presented. Bubbles are followed


Metal Enrichment of the Intergalactic Medium in Cosmological Simulations
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 -
Simulating IGM Reionization
We have studied the IGM reionization process in its full cosmological context including structure evolution and a realistic galaxy population. We have used a combination of high-resolution N-body
Starburst-driven galactic winds — I. Energetics and intrinsic X-ray emission
Starburst-driven galactic winds are responsible for the transport of mass, in particular metal-enriched gas, and energy out of galaxies and into the intergalactic medium. These outflows directly
Early Metal Enrichment of the Intergalactic Medium by Pregalactic Outflows
We assess supernova-driven pregalactic outflows as a mechanism for distributing the product of stellar nucleosynthesis over large cosmological volumes prior to the reionization epoch. Supernova (SN)
Galactic Winds in the Intergalactic Medium
We have performed hydrodynamical simulations to investigate the effects of galactic winds on the high-redshift (z = 3) universe. Strong winds suppress the formation of low-mass galaxies

Clustering of galaxies in a hierarchical universe - I. Methods and results at z=0
We introduce a new technique for following the formation and evolution of galaxies in cosmological N-body simulations. Dissipationless simulations are used to track the formation and merging of dark
Violence in the dark ages
A wide range of observational and theoretical arguments suggest that the universe experienced a period of heating and metal enrichment, most likely from starbursting dwarf galaxies. Using a
