The Nature of Luminous Quasars with Very Large C IV Equivalent Widths
Shuqi Fu, W. N. Brandt, Fan Zou +5
We report results for a complete sample of ten luminous radio-quiet quasars with large C IV equivalent widths (EW > 150 A). For 8/10 we performed Chandra snapshot observations. We…

Evolution of X-ray Activity in <25 Myr Old Pre-Main Sequence Stars
Konstantin V. Getman, Eric D. Feigelson, Gordon P. Garmire +4
Measuring the evolution of X-ray emission from pre-main sequence (PMS) stars gives insight into two issues: the response of magnetic dynamo processes to changes in interior structu…

Sensitive Chandra coverage of a representative sample of weak-line quasars: revealing the full range of X-ray properties
Q. Ni, W. N. Brandt, B. Luo +8
We present deeper Chandra observations for weak-line quasars (WLQs) in a representative sample that previously had limited X-ray constraints, and perform X-ray photometric analyses…
