Ionization structure of the warm wind in NGC 5548
K. C. Steenbrugge, J. S. Kaastra, D. M. Crenshaw +7
We present the results from our 140 ks XMM-Newton and 500 ks Chandra observation of NGC 5548. The velocity structure of the X-ray absorber is consistent with the velocity structure…
Atomic X-ray Spectroscopy of Accreting Black Holes
Duane A. Liedahl, Diego F. Torres
Current astrophysical research suggests that the most persistently luminous objects in the Universe are powered by the flow of matter through accretion disks onto black holes. Accr…
An Assessment of the Fe XVIII and Fe XIX Line Ratios from the Chandra Grating Observations of Capella
P. Desai, N. S. Brickhouse, J. J. Drake +8
Observations of Fe XVIII and Fe XIX X-ray, EUV, and FUV line emission, formed at the peak of Capella's (alpha Aurigae) emission measure distribution and ubiquitous in spectra of ma…
Resonant Auger Destruction and Iron K-Alpha Spectra in Compact X-ray Sources
Duane A. Liedahl
We examine the effects of resonant Auger destruction in modifying the intensities and flux distributions of K-alpha spectra from iron L-shell ions. Applications include X-ray irrad…
Simultaneous X-ray and UV spectroscopy of the Seyfert 1 galaxy NGC 5548.II. Physical conditions in the X-ray absorber
K. C. Steenbrugge, J. S. Kaastra, D. M. Crenshaw +8
We present the results from a 500 ks Chandra observation of the Seyfert 1 galaxy NGC 5548. We detect broadened emission lines of O VII and C VI in the spectra, similar to those obs…
