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…
The Flux Auto- and Cross-Correlation of the Lyman-alpha Forest. II. Modelling Anisotropies with Cosmological Hydrodynamic Simulations
Andrew R. Marble, Kristoffer A. Eriksen, Chris D. Impey +2
The isotropy of the Lyman-alpha forest in real-space uniquely provides a measurement of cosmic geometry at z > 2. The angular diameter distance for which the correlation function a…
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…
