We present evidence for X-ray absorption by ionized oxygen in ASCA spectra of the prototype infrared quasar IRAS 13349+2438. This powerful (Lbol > ∼ 2× 10 46 erg s) quasar was studied in detail with ROSAT , and the combination of the X-ray data and optical/near-infrared spectropolarimetry strongly suggested the presence of a dusty ionized (‘warm’) absorber… CONTINUE READING
