Scientific paper

Recent optical spectroscopy has identified a large sample of SDSS quasars (QSOs) with broad CIV and/or MgII absorption lines (BALs). The relationship between UV and X-ray absorbers/continuum is controversial, with important implications for models of QSO structure. Short, 10 ks observations of X-ray bright BALQs will give CCD X-ray spectra enabling us to measure and constrain absorber states, continuum properties, and Fe Ka lines, with ramifications for BALQ structure. Our targets are unusually X-ray bright for BALQs. Understanding these exceptional sources will shed light on the physics of BALQs in general. Our sample includes four radio-loud and two low-ionization BALQs; high-counts X-ray spectra of such objects are rare.
