We present predictions for the cosmic metal budget in various phases of baryons from redshift z = 6 → 0, taken from a cosmological hydrodynamic simulation that includes a well-constrained model for enriched galactic outflows. We find that substantial amounts of metals are found in every baryonic phase at all epochs, with diffuse intergalactic gas dominating the metal budget at early epochs and stars and halo gas dominating at recent epochs. We provide a full accounting of metals in the context…

The evolution of the baryon distribution in the universe from cosmological simulations
The evolution of the baryon distribution in different phases, derived from cosmological simulations, are here reported. These computations indicate that presently most of baryons are in a warm-hot
Balancing the baryon budget: the fraction of the IGM due to galaxy mergers
Observations indicate that roughly 60 per cent of the baryons may exist in a warm-hot intergalactic medium (WHIM) at low redshifts. Following up on previous results showing that gas is released
The enrichment history of cosmic metals
We use a suite of cosmological, hydrodynamical simulations to investigate the chemical enrichment history of the Universe. Specifically, we trace the origin of the metals back in time to investigate

The intergalactic medium over the last 10 billion years – I. Lyα absorption and physical conditions
The intergalactic medium (IGM) is the dominant reservoir of baryons at all cosmic epochs. In this paper, we investigate the evolution of the IGM from z = 2 → 0i n (48h −1 Mpc) 3 , 110million particle

By means of chemo-photometric models for galaxies of different morphological types, we have carried out a detailed study of the history of element production by spheroidal and dwarf irregular
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

Using the guidelines on supernova element production provided by XMM-Newton, we summarize the results of ASCA observations on the element abundance in groups and clusters of galaxies. We show that

Baryons in the warm-hot intergalactic medium
Approximately 30%-40% of all baryons in the present-day universe reside in a warm-hot intergalactic medium (WHIM), with temperatures in the range 105 < T < 107 K. This is a generic prediction from
