Abstract

We present results from a high resolution cosmological simulation of galaxy formation in a cold dark matter universe, focusing on a redshift of 3. At this early time, star formation (which we follow using a multiphase prescription for the ISM) is occurring vigorously, but most of the baryons in the universe are still diffuse, and have yet to form into galaxies. Absorption lines due to neutral hydrogen in the spectra of nearby quasars provide a useful way to probe physical conditions in the gas around the galaxies. We make simulated spectra, compare them with observational data, and draw some conclusions about the relationship between galaxies, star formation, and the IGM.
