IR Spectroscopy of High-Redshift Quasars
Published online by Cambridge University Press: 12 April 2016
Abstract
We have obtained near-IR, optical, and soft X-ray spectrophotometry for a number of bright quasars with 2 ≲ z ≲ 4. The observed ratios of Lyα/Hβ in this sample are smaller than Case B, and span a similar range to those seen at lower redshift. A correlation between the line width of Hβ and X-ray spectral index found for low-redshift PG quasars is also seen for the high-redshift objects.
