Title: Intergalactic Heavy-Element Enrichment at z 6
Abstract: We propose to continue our moderate resolution J band spectroscopy of two z\gtrsim 6 QSOs, to survey the distribution of carbon and silicon in the intergalactic medium when the universe was \le 1 Gyr old. These data will be used to study the evolution of cosmic carbon abundances with redshift, as well as the spectrum of the background radiation field at the end of the reionization epoch.
