Evolution in the Frequency of Heavy Element Absorbers Approaching the Epoch of Reionization
Abstract
This contribution will summarize recent observational results on the high-redshift intergalactic and circumgalactic media from spectroscopy of Lya and metal lines between 3 and 7. A particular emphasis will be given to searches for heavy element absorption in the infrared spectra of newly-discovered QSOs at z > 6.5.
