The Nature and Origin of Low-Redshift O VI Absorbers
Benjamin D. Oppenheimer, Romeel A. Davé
The O VI ion observed in quasar absorption line spectra is the most accessible tracer of the cosmic metal distribution in the low redshift (z<0.5) intergalactic medium (IGM). We ex…
Enrichment and Pre-Heating in Intragroup Gas from Galactic Outflows
Romeel Davé, Benjamin D. Oppenheimer, Suresh Sivanandam
We examine metal and entropy content in galaxy groups having T_X~0.5-2 keV in cosmological hydrodynamic simulations. Our simulations include a well-constrained prescription for gal…
Mass, Metal, and Energy Feedback in Cosmological Simulations
Benjamin D. Oppenheimer, Romeel Davé
Using Gadget-2 cosmological hydrodynamic simulations including an observationally-constrained model for galactic outflows, we investigate how feedback from star formation distribut…
When Does the Intergalactic Medium Become Enriched?
Benjamin D. Oppenheimer, Romeel Davé, Kristian Finlator
We use cosmological hydrodynamic simulations including galactic feedback based on observations of local starbursts to find a self-consistent evolutionary model capable of fitting t…
The Mass-Metallicity Relation in Cosmological Hydrodynamic Simulations
Romeel Daveé, Kristian Finlator, Benjamin D. Oppenheimer
We use cosmological hydrodynamic simulations with enriched galactic outflows to compare predictions for the galaxy mass-metallicity (M*-Z) relation versus observations at z~2 from…
Constraints on Physical Properties of z~6 Galaxies Using Cosmological Hydrodynamic Simulations
K. Finlator, R. Dave', B. Oppenheimer
We conduct a detailed comparison of broad-band spectral energy distributions of six z >= 5.5 galaxies against galaxies drawn from cosmological hydrodynamic simulations. We employ a…
