Group Scaling Relations From a Cosmological Hydrodynamic Simulation: No Pre-heating Required?
Romeel Davé, Neal Katz, Lars Hernquist +1
We investigate the X-ray vs. optical scaling relations of poor groups to small clusters (sigma~100-700 km/s) identified in a cosmological hydrodynamic simulation of a Lambda-CDM un…

Enrichment of the High-Redshift IGM by Galactic Winds
A. Aguirre, J. Schaye, L. Hernquist +3
This paper discusses a semi-numerical method of investigating the enrichment of the intergalactic medium by galactic winds. We find that most galaxies at z >~ 3 should be driving w…
