“…Recently, evidence has accumulated that some warm absorbers contain significant amounts of dust (B96, Komossa & Fink 1996, Komossa & Fink 1997b-d, Reynolds et al 1997, Leighly et al 1997, Komossa & Bade 1998, Komossa 1998. The possibility of a dusty warm absorber in IRAS 13349 was suggested by B96 to explain the lack of excess X-ray cold absorption despite strong optical reddening (for follow-up ASCA observations see Brinkmann et al 1996, Brandt et al 1997. As emphasized by Komossa & Fink (KoFi hereafter, e.g.…”
