Scientific paper

The SDSS has discovered a mysterious class of radio-quiet and radio-moderate quasars at high redshift with no or extremely weak high-ionization emission lines. These weak-line quasars (WLQs) may have "anemic" high-ionization Broad Line Regions, or they may have relativistically boosted optical/UV continua (as for BL Lacs). We propose exploratory Chandra observations of 9 WLQs that will nearly triple the sample with sensitive X-ray coverage, allowing the first reliable characterization of their basic X-ray properties. By probing their inner accretion regions, we aim to assess the current explanations for WLQs and their implications for, e.g., emission-line formation, high-velocity outflows, and relativistic jets.
