16 Oct 1999 | | Subject: | astro-ph | | Affiliation: | Penn State), A. Laor (Technion), Beverley J. Wills (UT Austin | | Abstract: | Major flows of ionized gas are thought to be present in the nuclei of most luminous QSOs, and absorption by these flows often has a significant effect upon the observed X-ray continuum from the black hole region. We briefly discuss X-ray studies of this gas and attempts to determine its geometry, dynamics, and ionization physics. Our focus is on X-ray warm absorber QSOs, Broad Absorption Line QSOs, and soft X-ray weak QSOs. We also discuss some prospects for further study with the next generation of X-ray observatories. | | Source: | arXiv, astro-ph/9910302 | | Services: | Forum | Review | PDF | Favorites | |
