Star Formation and Chemical Evolution at High Redshift

  title={Star Formation and Chemical Evolution at High Redshift},
  author={Chip Kobulnicky},
I review the observational characteristics of intermediate-to-high redshift star forming galaxies, including their star formation rates, dust extinctions, ISM kinematics, and chemical compositions. I present evidence that the mean rate of metal enrichment, Delta{Z}/Delta{z}, from z=0--3, as determined from nebular oxygen abundance measurements in star forming galaxies, is 0.15 dex per redshift unit for galaxies more luminous than M_B=-20.5. This rate of chemical enrichment is consistent with…
