The Frequency of Intrinsic X-Ray Weakness among Broad Absorption Line Quasars
We present combined 14-37 ks Chandra observations of seven z = 1.6-2.7 broad absorption line (BAL) quasars selected from the Large Bright Quasar Survey (LBQS). These seven objects are high-ionization BAL (HiBAL) quasars, and they were undetected in the Chandra hard band (2-8 keV) in previous observa...
